Flora & Fauna 
This wilderness is home to black bears, mountain lions, elk, and bighorn sheep. Forested areas consist predominantly of spruce and aspen.
The Peaks had traditional and religious significance to the region's early Spanish settlers, hence the name, which means "Blood of Christ".
The faulted and uplifted mountains of the Sangre de Cristo are geologically distinct from the Spanish Peaks range to the east.
