Spring is Sprung!

Matching funds grant awarded to Black Hills Wild Horse Sanctuary!

We've qualified for a matching funds grant to install an irrigation system on 400 acres of land!  This will improve grazing and hay production both of which helps feed the wild horses!  Can you make a donation to help us reach this goal??  

Enhancing the natural water resources by modernizing the 140 year old irrigation system and expanding to cover 400 acres! The increased grazing land and improved hay fields will make feeding the wild horses less expensive while reducing our dependance on outside sources.

Our Mission
The Institute of Range and the American Mustang (IRAM) founded by Dayton O. Hyde in 1988 is a 501 c 3 non profit registered in the state of South Dakota. Our Federal Tax number is 46-0401462. IRAM's finest gift is the Black Hills Wild Horse Sanctuary home to hundreds of unwanted wild mustangs. 

Join The Herd

You can sponsor Cassidy in the curly horse herd!  Her warm brown eyes invite you to come over and say hello!


You will feel them before you hear them

You will hear them before you see them.


There on the horizon, stretch the sources of the thunder. Neither men nor machines nor the timeless rumblings of a prairie storm.


They are the wild mustangs, and they are home at last!
