Sand Wash Advocate Team

an on the range program of the Great Escape Mustang Sanctuary

The Sand Wash Advocate Team


SWAT is an on-the-range project of the Great Escape Mustang Sanctuary and was formed in 2012, recognizing a need to organize the energy and efforts of individuals and groups in supporting the Sand Wash Basin (SWB) land and wild horses. SWAT is 100% volunteer-driven. Volunteers perform all of our administrative work, planning and coordination, field work, research, data collection and analyses, marketing and Internet activities. Financial support for this program is provided through our memberships. 100% of every dollar received goes towards advancing SWAT’s mission to, as citizen stewards, support the Sand Wash Basin land and wild horses in collaboration with the Bureau of Land Management. Our collaboration of support focuses on fertility control, herd documentation and gather support. 


  1. Access to a private member only Facebook group that will give you more detailed access to herd documentation statistics, and news from the Basin.

  2. You will be invited to join SWAT members and GEMS staff at an exclusive retreat at our beautiful off range dedicated ranch and sanctuary.  We’re home to over 50 wild mustangs and burros, which include 13 Sand Wash Basin Mustangs, Spanish Mustangs, our trained Ambassador Mustangs and others that are in our training and adoption program.  Members will also receive a monthly membership e-newsletter on the happenings in SWB and at GEMS.

  3. You will be invited to join SWAT members and GEMS staff at our annual SWAT Rendezvous in Sand Wash Basin.  This event will include knowledgeable insight of the range and the horses, from us, your on the ground SWAT team.  This is a fun, family friendly day and camping event for folks to enjoy the range we support.  In 2018 we will not be completing a work project, we will just have fun!

  4. A custom SWAT t-shirt to show your support for the wild horses everywhere you go!
