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.

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.
