HuntScore Tip

Public land and private land percentages can sometime be misleading. A unit may have 80% public land, but a particluar species may only occupy 20% on the entire area. And that 20% species distribution may lie 100% within private lands. Does that sound confusing? Just remember that there are always exceptions to the rule, and land ownership is just one piece of the puzzle.

Photos and Terrain Notes

The Continental Divide and the Gore Range Divide encircle Middle Park. Most of this terrain is steep to very steep. Sagebrush/shrubs are common on southern exposures at lower elevations. The past decadefts mountain pine beetle killed an estimated 80 percent of mature lodgepole pine trees in Grand County, creating numerous hazards along public roadways as these trees begin to fall.

Middle Park is a large basin surrounded by high mountain ranges. As an inter-mountain park it is unique in two respects. It does not have the level interior characteristic of other large mountain parks in Colorado, such as North Park and South Park, and it lies west of the Continental Divide. The Troublesome Creek area has numerous peaks along the Continental Divide reaching altitudes above 13,000 feet.

The highest of these is North Arapaho Peak at 13,502 feet in the southeast corner of the area. All the natural surface drainage for this area funnels through Gore Canyon, downstream from Kremmling. Vegetation in Middle Park can be categorized into five broad types Ò cropland, wetland/riparian, rangeland, forestland and alpine. The variety of vegetation types scattered throughout Middle Park creates a highly desirable mosaic very beneficial to wildlife.

However, plant communities at lower elevations are becoming increasingly disturbed by intensive human use.

Croplands consist of irrigated hay meadows and terraces that have been re-seeded to desirable forage plants. Most hay ground is \native hay

Weather Insights

Weather can vary by elevation. See how weather varies by elevation within a unit by selecting an elevation range. Elevation ranges are based on weather stations in or near the unit. Not all weather elements are available within the unit.

Average Temps

Use temperature ranges to plan and prepare for your hunt. Large swings indicate a good layering system should be used. Be sure to make note of the extreme temperatures as these often pose the greatest risk to hunters. If you plan on hunting in higher elevation, as a rule of thumb, expect the tempture to decrease roughly 5° for every 1000' in elevation gain.
