Krista Nelson, Director of Indigenous Perspectives and Land Relationship
In the Lenape language, Krista is said to be a Lenapei Lixsewakani Wintemakwi ok Kikehwèt Hitkwike — a Lenape language teacher and healer among the trees.
Krista teaches the Lenape language as an act of cultural revitalization and shares it in living relationship with the land. Kweteli Chich is a Lenape mourning song she composed as a bridge between language and grief work. It is offered as both a cultural expression and a living practice—a way to grieve, remember, and honor those who have passed, as well as express a joyful commitment to love and living. Krista’s remix of the Native American legend of the first flute, Woodpecker’s Gift brings an ancient language to new audiences popular with all ages.
As a ritual guide, Krista leads hikes and gatherings rooted in seasonal wisdom—offering gratitude rituals, rites of reciprocity, and nature-based practices such as her signature Creek Drinking; responding to the musical gifts of water with the music of our own making.
Krista is the author of Create Your Dream Life in 6 Steps or Less – A practical guide for personal transformation through journaling and visioning. She has also written a 12-book self-development series designed to immerse readers in the act of communing with nature through her photographs of the Wissahickon Valley Park.
Whether guiding a grief walk through a cemetery, inviting people to heal through song, or learn how to hold clinical therapy sessions outdoors, Krista holds space for transformation grounded in respect, belonging, and the sacred rhythms of the natural world. www.kristaunearthed.com | @knelsonauthor
