Moriah Helms

Semester Program, Rising Moon Facilitator

Wilderness First Responder, BA Spanish, Middlebury College

Moriah has lived most of her life in the bio-region of so-called New England and currently lives on Penobscot territory in midcoast Maine. The daughter of a woodworker and a Waldorf educator, she spent her Vermont childhood climbing trees, traipsing through fields, foraging and gardening, while receiving a Waldorf education. She understands, from an embodied place, the deep value of unstructured experiential outdoor learning and nurturing young people’s innate creativity.

A passion for learning languages has led Moriah to study French, German, Spanish, Japanese, and other languages at various times throughout her life. She is looking forward to learning more Farsi and Irish in the coming year. Moriah facilitates a Spanish language learning component through story and song at White Ash on Wednesdays and Thursdays.

Moriah has been involved with The Wildwood Path in Unity, Maine for six years, first as a participant and then as staff, where she deepened her experience with shelter building, winter camping, friction fire, naturalist skills, medicine making, cordage, crafting, and tracing the lineages of story, song, and culture.

She is excited to be attending tracking workshops, and Animas Valley Institute programs in 2022, as well as continuing her own experimentation with various crafts — all of which she plans to bring to her work at White Ash Learning!

Moriah believes that the growing of a post-capitalist world must be accessible, collective, and adaptable. Her passion for history and anti-capitalist praxis has led to the creation of an online class for adults, Sowing Post Capitalist Seeds, in which participants explore the origins of capitalism and white supremacy, and work on creating alternatives in our lives and communities.

Mica Rose

Semester Program

Wilderness First Aid, BA Peace and Global Studies, Earlham College

Mica Rose was born and raised on unceeded land of the Powatan Confederacy, also know as Richmond Virginia, and has recently relocated to the Mid-Coast with their family. They received a Bachelor’s Degree in Peace and Global Studies from Earlham College, where they focused their interest in the role of art and imagination within social movements. They have received training in conflict transformation, collective decision making processes, and community trauma healing modalities. They are fascinated by neuroscience, human development, and how people learn and make sense of the world. They have worked with children for over 10 years in a variety of settings including 5 years in community arts programming, and three years working in Montessori classrooms.

One of their most cherished offerings is working with very little ones in the process of learning to read. They are committed to creating and facilitating spaces where children can be rooted, guided, and free. Mica believes strongly that cultivating radical imagination and connection to the more than human world in childhood is essential for raising people who can act in the world as change makers and caretakers. They build relationships with children with an anti-oppressive foundation, and believe that accommodating and respecting children’s autonomy and personhood is essential to true learning.

The journey of homeschooling/unschooling their now six year old has opened up more curiosity about alternative and community based educational models, and they are grateful to be a part of the White Ash community as a mentor and a parent of a participant. They are also a musician, writer, and multi-disciplinary artist. They can often be found singing to their plant friends in the garden, or giving offerings to streams, rivers, and other bodies of water. Click here to contact Mica.

Mev Grover

Semester Program

Wilderness First Aid, Certificate in Permaculture Design, Certified Sawyer

Mev grew up with hands and feet in the mud of the tidal wetlands of traditional Abenaki land known as Scarborough, Maine, studying hermit crabs and watching the cycles of the tides and moon. This deep connection with nature fostered a lifelong curiosity with all forms of the natural world, from fungi and lichens to ever shifting weather patterns. They soak up information about nature through podcasts, songs, books, and stories, and delight in sharing what they find with others. Mev has spent much of their adult life tending plants and working with the earth through gardening, farming, landscaping, and trail crew, and has spent many hours exploring woods and streams with the children in their life. They bring diverse experience from working with Meeting House Herb Farm, Local Sprouts Cooperative, and the Beehive Design Collective. They nurture a creative practice of visual art, theatre, and song. They seek to unweave their own capitalist and white supremacist conditioning, and re-weave social patterns of deep listening, accountability, and mutualism.

Leigh Seeleman

Rising Moon Facilitator

Wilderness First Responder, BA Environmental Studies, Biology Concentration, University of Pennsylvania

I grew up on Lenni-Lenape land with my parents and grandparents who joined me in wandering up brooks, marveling at crickets, lightning bugs, chickadee, black eyed susan and dandelion.  My love for the wild and my grief for environmental destruction led me to the concrete jungle of Philadelphia and the tropical forests of Costa Rica and Nicaragua to study environmental science.

While living in Philadelphia I supported students to connect with nature through teaching in a variety of settings including on a sailboat with Philadelphia CitySail, with Philadelphia Outward Bound, Girl’s Leadership Camp, Environmental Education Camp, and in classrooms and afterschool programs.  I also began to study and play at creative movement, song and music-making, wilderness awareness, women’s blood mysteries, rites of passage guiding, urban farming, herbalism, dreaming practices, massage therapy and healing arts. Participating in Niyonu Spann’s Beyond Diversity 101 curriculum gave me tools for the ongoing life-work of uprooting systematic oppression and taking actions toward creating a culture of equity.

I enjoy tending plants, weaving story, poems, performance art, song, music and dance, praising the wild ones in nature and giving my heart to the story of collective liberation. I love creating spaces for young people to be free, curious and connected with the wild within and around. I have a professional healing arts practice in the midcoast area and Philadelphia offering massage, bodywork, energy healing, mentoring & dreamwork. Click here to contact Leigh.

Gabrielle McSherry (she/her, they/them)

Semester Program Substitute Mentor

Wilderness First Aid, BFA Sculpture, Literary Arts Concentration in Gender, Sexuality, and Race
Rhode Island School of Design

Gabrielle has taught and worked with the young ones in the arts and outdoors both in the U.S. and abroad for the last 10 years. Hailing from the deep south, as a child they grew nourished by the great blue shores of Seminole and Tocobaga land, what is now known as the Gulf of Mexico and Tampa Bay,  Florida. Leaving the grandness of Live Oaks she was confronted with a very different landscape moving to the territory of the Onondaga Nation of so called Syracuse, New York at 11. Here they learned to embrace the crisp cold that moved from the Great Lakes over the region bringing heavy snow and darkness.

Gabrielle attended college at Rhode Island School of Design in so called Providence, RI on the land of the Narragansett People. She studied in the sculpture department learning woodworking, casting, and metalworking skills, which she applied to her full bodied performance work that invoked much of what she now calls ritual, healing, and ancestral medicine. RISD gave her the skills to examine, question, imagine, and interpret her environment, which they now apply to much of their work in de-colonization, and anti-capitalism. Using their creativity and commitment to anti-racism, anti-oppression, and disability justice they work hard to imagine new realities of liberation. With the help and collaboration of their ancestors, the more then human world, the young ones, and their community they are moving these dreams into reality. Although she is a widely self-taught herbalist, Gabrielle can recall the seeds sowed from Ihre Oma (her grandmother) who moved to the “U.S,” in her 20s from the Rhine River region of Germany. Ihre Oma has always used plant medicine to heal and would give young Gabrielle spoonfuls of honey and lemon, nibbles of garlic, and chamomile tea when they were sick. She began deepening her relationship with plant medicine studying with Mary Blue of Farmacy Herbs in the Fall of 2014. This was brought on by illness and burnout. This time of illness was an important initiation into shadow work and set her onwards towards healing their trauma. While at RISD, Gabrielle also earned a literary arts concentration in Gender, Sexuality, and Race. In this study she was able to give language to her Queerness and name parts of herself that had been hidden by heteronormativity.

In 2016, she moved away from PVD to study with Tom Griffin and Amanda Labelle of Hope’s Edge Farm in what is now know as Hope, Maine on Penobscot Territory. Gabrielle worked at Hope’s Edge Farm for two years where she studied biodynamic agriculture and began a mentorship with Deb Soule of Avena Botanicals, where she has taken courses. Since then she has furthered her relationship to plants through studying with herbalist Jillian Hyllantree Twisla, Suzanne Stone of Moon of Hyldemoer Herbals, she has also attended the New England Women’s Herbal Conference, and the International Herbal Symposium. This summer 2022 they will be participating in the Plant Spirit Medicine Course offered by Jillian. Gabrielle hopes to continue cultivating more profound and genuine relationships with the plant world who have so generously loved and cared for her.

In the winter of 2019, Gabrielle met the sweetness that is her now partner Audrey. Together, in the backcountry, along the Dead River and the mountains of what is Abenaki territory in western “Maine”, Audrey and Gabrielle imagined new kinds of care and formed a relationship of nurturance and safety. Now Audrey and Gabrielle live near the Penobscot Bay in the town of “Monroe” in a small home they built themselves. They are both excited to work on a fun creative project they call “Chainsaw Witch” which intersects tree work, forest skills, tree worship, radical queerness, feminism, anti-racism, self-care, and plant medicine.

Right now, Gabrielle is excited to learn ASL, tend to a small humble garden, harvest plant medicine, be embodied while working with the struggles of c-ptsd, embrace and grow slowness and self-care, dance, cook, continue deepening and embodying anti-racism and de-colonial work, and be more passionately in belonging with themselves and their ancestors. And to bring all of this, with them, in wholeness while communing with the young ones at White Ash Learning and everywhere. Click here to contact Gabrielle.

“Young people are the next generation and it is vital to take care of them and encourage loving connection with that which surrounds them, feeds them, helps them breath, and is apart of them.”

Audrey Burns (she/her, they/them)

Semester Program Substitute Mentor

Wilderness First Responder, BS Natural Resources, Green Building & Community Design Minor, University of Vermont

Audrey was born on the salty shores of Wampanoag and Pokanoket land in Mattapoisett, Massachusetts. She and her brother were raised by a working class carpenter and a potter and could usually be found swimming, catching crabs, skateboarding, riding bikes off the wharf into the harbor, looking for forgotten money in the pants pockets at the Salvation Army, and building hideaways in the woods. Audrey’s love for the place where the woods meet the ocean, and strong cultural and family pressure drew them to study Natural Resources and Green Building/Community Design at the University of Vermont. Audrey studied wilderness theory, trip leading, eco/living machines, government forest management and policy, critiques of capitalism and environmental movements, and became certified with the American Canoe Association as Canoe Instructor. Audrey started her career and a trail builder, leading canoe trips and designing and maintaining trails and campsites with the Northern Forest Canoe Trail. Seeking escape, change, expansion, adventure and the big sky, Audrey packed up and took a train to the northern Rockies to build and maintain trails with hand tools in the “Forest Service Wilderness”, some of the most remote places in the lower 48 states and the stolen lands of the Nimiipuu, Shoshone-Bannock, Kalispel, Salish, Blackfoot, Metis, and Crow peoples. She became practiced in the arts of the chainsaw, crosscut and axe. Audrey met a scientist and studied with him in the foothills of the amazon basin in Peru, observing both butterflies and violence of science.  Audrey returned home after learning of the sudden death of their father, Dennis, in 2015, and continues to learn how to celebrate and honor, and to grieve his influence and memory.

After spending two years closer to home as an Outward Bound instructor/science curriculum facilitator and an island caretaker, Audrey moved west again to work maintaining trails and historic cabins, riding and packing horses and mules, and canoeing and kayaking the alpine lakes of Yellowstone National Park as a backcountry ranger. In the winter between Yellowstone seasons, Audrey returned to western Maine for off season work where she was brought together for the first time with her current partner, Gabrielle, when they crossed paths on a snowy trail near the drowned town of Flagstaff. They spent the winter supporting each other through 16 hour work days and finding deep connection and nurturance in the woods above Spencer Stream and the Dead River.

Audrey was called back to the place where the north woods meet the ocean. She spent the last years designing and building a home with her partner, Gabrielle. Audrey is pursuing education and community around her passions of tree work and motorcycles.  They are currently working toward certification as a Registered Maine Guide. She enjoys cooking as a way to communicate with her ancestors and is on the beginning of her journeys to study ASL and the Irish language.

Audrey is excited to share their skills, imagination, curiosity, and wildness with the young people being grown in this place.

Jason Millis Chandler

Wilderness First Responder, Maine Master Naturalist
Registered Maine Guide, BA Philosophy, Vassar College

I grew up following my imagination in cliffy spruce woods, roaming tide pools in rocky sandy shores, kayaking in my father’s hand-built boats, marveling at the sky, role-playing in games and on stage, seeking acclaim where I could find it, and sometimes obeying my mother and picking sweet peas and strawberries in the garden above a peninsular harbor in Small Point, ME. I learned inextricably from a young age that all life on earth is both completely amazing and in danger due to our human actions. As soon as I could, I got out of school and walked from Maine to Georgia on a footpath popular even in the gruesome yet budding 21st century. I found myself soon back in classrooms at the dream-realm of Vassar college and studying abroad in Tibetan communities, reveling as an outsider in language and old culture, glimpsing some of the faces of active genocide. Sickened by grief on my return, and emboldened by the practices of living outdoors, I sought life outside of the U.S. for some perspective that might help me, help us. I lived as a student, outdoor educator and Peace Corps volunteer in Armenia for two years. I taught at Chewonki. I led teenagers on expeditions along the coast of present Wabanaki land, to the mountains on foot, and into northern Maine and Quebec in that magnificent indigenous technology the canoe. Then, somehow lost and wild and longing, I met Caitlin Thurrell and she asked me for a walk in the woods. I gave her a bowl carved of Apple wood. After nine years of study and the practice of farming, she was returning to Ladakh in the Himalayas to live. She said she was going alone. I wanted more than anything to be with her, and through some grace she finally said yes. We split our lives now between a small village there through a gorge above the Indus named Dar, where we help grow barley and wheat and take sheep and goats to the mountains, and coastal Maine where we have recently made a small cedar and straw and clay cabin we call home. Receiving and remembering such incredible gifts in life, I want to pass the best I can along to the coming generations, knowing that all we can do is prepare and practice for the unknown.

Caitlin Thurrell

Rising Moon Facilitator

Wilderness First Responder, BA Human Ecology, College of the Atlantic

I grew up a little queer in queer family among the foothills and waters of central New Hampshire, Abenaki Territory, mostly inside of doors and books. Only at last I turned outward to bring attention to rest (as it does still) in the greater-than-human world of root, leaf, and flower, track and skin and hollow bone. When I was eighteen I left high school and worked hard, supported by my parents, to earn money to travel to India.

The experiences of those ten months changed and opened many things in my mind and heart, including a beginning of my own journey understanding interdependence, suffering, whiteness, colonization, and capitalism, and also a deep hope that humans can live a different way, bringing more beauty and less harm. In the spring of that year I spent one month in Ladakh, returning then to the US with powerful desire to go back someday with more ability to be useful. Following this wish I left Brown University for the island called Mount Desert in English, Wabanaki Territory, to study Human Ecology, weave apprenticeship in sustainable agriculture with field natural history, art making, and wisdom-tradition philosophy. Finding work then as farmer and educator on a peninsula called Chewonki in corruption of its original name, I was given the office of Sunrise and came to love the mudflats and salt marshes, spartina and mink tracks in heavy clay. After these nine years training, I began to feel prepared.

Jason and I met and fell in love that year, traveled down the Kennebec River from its headwaters to the sea, and then continued our journey to the Northern Himalaya. Through volunteer teaching at the Students’ Educational and Cultural Movement of Ladakh (SECMOL) we met Chondol and came home with her to her village of Tar in Sham, western Ladakh, where apricot trees bloom in springtime over two-thousand-year-old fields of barley. In this village of thirteen households and many elders the strength and labor of our young bodies felt helpful, and we could learn some of the labors and songs of making life in this high altitude desert.

Now we have built a small house together in Wabanaki Territory, downeast of Ellsworth, and are making an effort to live ethically in and between these places, in good respectful relationship with community and land.

So far in my life I have served as reader and writer, quiet woods-walker, farmer (apprentice, journey person, and practitioner), teacher of soils, wood, forests, mountains, and waters, cooking on fires, and song. I strive to be a mindful student of solitude and death.

I love dancing and making art with natural materials, song, human and draft powered grain, vegetable, and medicine cultivation, and silent mountain sitting practices of attention. Being with young people out of doors, playing or working or sitting quietly watching and learning brings great joy and hope. Click here to contact Caitlin.
