Unit 591
PUEBLO/FREMONT/EL PASO
Fort Carson military reservation spanning foothills and plains with sparse timber and limited water.
Hunter's Brief
Unit 591 sits on Fort Carson Military Reservation, spanning transitional terrain between the plains and foothills with scattered ponderosa and juniper covering rolling to gently sloping country. Elevations range from mid-5000s to near 7000 feet across a landscape dominated by open grasslands interspersed with small timber stands. Access is restricted to authorized hunters and limited to designated roads and trails; water sources are scattered through small reservoirs and seasonal creeks. Expect lower hunting pressure due to access limitations and military use patterns.

Terrain Deep Dive
Landmarks & Navigation
Timber Mountain, Wild Mountain, Buck Hill, and White Butte provide prominent reference points for navigation and glassing across the rolling terrain. The Red Creek system—both East and West forks—serves as a major drainage corridor through the unit. Several named valleys including Orchard Canyon, Sullivan Canyon, and Rule Canyon offer natural travel routes and hunting prospects.
Multiple reservoirs (Haymes, Fountain, John Townsend, Teller) mark water locations useful for both navigation and logistics planning.
Elevation & Habitat
Terrain ranges from mid-5000-foot prairie through rolling foothills approaching 7000 feet, with most country in the moderate elevation band. Habitat transitions from open grasslands at lower elevations to scattered ponderosa and juniper stands on slopes and ridges. The country is predominantly open with sparse timber—expect dry, grassy valleys broken by occasional timbered draws and ridges rather than heavily forested slopes.
Vegetation follows typical Front Range transition zone patterns, with dominant sagebrush, yucca, and native grasses interspersed with scattered conifers.
Access & Pressure
Fort Carson Military Reservation status dominates access considerations—hunting requires specific authorization and adherence to military protocols. A sparse road network of roughly 55 miles provides limited connections across the unit, suggesting moderate to low pressure patterns. Access points and legal hunting areas are restricted by military operations and security zones, making pre-hunt verification essential.
The combination of military use and limited road density means most of the unit receives lighter pressure than typical public land, but accessible areas may concentrate hunters near those limited corridors.
Boundaries & Context
Unit 591 encompasses portions of Pueblo, Fremont, and El Paso counties entirely within Fort Carson Military Reservation boundaries. The unit spans transitional terrain between the high plains to the east and the foothills rising toward the Front Range to the west. Stone City and associated communities mark the general area, though the unit itself is military-controlled land with specific access protocols.
The reservation's boundaries define the unit's extent, making orientation to those limits critical for hunters.
Water & Drainages
Water is limited and scattered across the unit, making strategic hunting dependent on locating reliable sources. Small reservoirs including Haymes Reservoir, Fountain Reservoir, and John Townsend Reservoir provide dependable water where they exist. The Red Creek system and Little Turkey Creek offer seasonal to reliable flows depending on precipitation and spring timing.
Several irrigation ditches (Lytle, Strobel, Merriams Rock) follow lower terrain, providing supplemental water in their reaches. Spring conditions and reservoir levels should inform hunting location planning.
Hunting Strategy
The unit holds elk, mule deer, white-tailed deer, pronghorn, moose, mountain lion, and black bear historically, with habitat supporting these species across elevation zones. Lower-elevation grasslands suit pronghorn and mule deer, while scattered timber on rolling terrain provides elk and white-tailed deer habitat. The transitional nature of the landscape means hunters should focus on brushy draws and canyon bottoms early season when water concentrates game, shifting to higher ridges and timber as temperatures cool.
Success depends on locating water sources and navigating access restrictions—verify current Fort Carson hunting regulations and access areas before planning.
