She has spent the past 20+ years in the Rocky Mountains and Southwest working as a Geologist and educator. She has a bachelor’s degree in Geology from Gustavus Adolphus College in Minnesota, her home state, and a master’s degree in Education from Adams State University.

Reece Wells

Camp and Family Programs Manager
reece@yampatika.org

Reece is originally from Denton, TX, and has been obsessed with nature since he first started cataloging the animals found on his family’s Ranch in the scraggly desert of Southwest Texas. From city parks to winding rivers and expansive lakes to wild, remote places, he loves getting to experience the thought-provoking beauty that nature provides everywhere. Even more, he loves getting to share that beauty and intentionally provokes the thoughts of others. Reece majored in Environmental Science in college with the main goal of always wanting to work outside. Luckily enough, he has been able to do that, leading and directing Camping and Outdoor Education programs in Colorado, Texas, Washington, and Wisconsin. Colorado has always been one of his favorite places because of the amazing nature and unique people. In his free time, you’re likely to find him hiking, backpacking, skiing, biking, or chilling in a hammock with a good book. One of his favorite parts about working with kids at Camp is playing games, of which he always has a few up his sleeve.

​Halie grew up in the Sandhills of North Carolina, riding horses in endangered Longleaf Pine savannahs, and went on yearly family ski trips to Sun Valley, Idaho. These childhood experiences fueled her passion for outdoor sports and environmental stewardship. She obtained a B.S. in Sustainable Development from Appalachian State University and a graduate certificate in Climate Adaptation from NC State University. Halie has held many positions in outdoor and environmental education: including ski instructor, wrangler, compost tea brewer, and zero-waste educator, to name a few. In her leisure time, Halie can be found skiing, hiking, paddle boarding, or most likely, spending quality time with her horse, Leo, and her bunny, Maple.

 In Memorium of Sue Hansen

On October 11th, 2022, Sue passed away surrounded by friends and family. She will be missed after years of working in the Yampatika family.

All who knew her could feel Sue’s caring spirit and generous heart. She was a lover of the outdoors and spent much of her time in the mountains enjoying the serene beauty they encompass. Sue was one with nature, especially amongst the wildflowers, which brought out the happy and free spirit that defined her. She was a bright and shining soul and a reminder to live fully with eyes wide open. Sue was a beacon of light and a steward in the community whose dedication toward all things good will be appreciated for years to come.
