| Mountain range | Presidential Range · within the White Mountains (Wikidata) |
|---|---|
| County | Coos County |
| Town / township | Thompson And Meserves Purchase |
| Summit | 5,712 ft / 1,741 m |
| USFS trailhead used for comparison | Caps Ridge Trailhead: 3,006 ft (1.9 mi from summit, straight line) |
| Elevation difference | 2,706 ft from Caps Ridge Trailhead to summit |
Altitude note (estimate): using the standard lapse rate of about 3.5°F per 1,000 ft, expect the summit to be roughly 9°F colder than the trailhead, before wind chill. Above treeline, wind can make it feel far colder.
Effort score: 1,424 ft/mi — Steep
Effort score = elevation gain ÷ straight-line distance from the nearest USFS trailhead to the summit (feet per mile). Trails wind, so real trail grades are gentler than this number. Under 500 Gentle · 500–999 Moderate · 1,000–1,499 Steep · 1,500+ Very steep. Use it to compare peaks, not as a trail grade.

Calculating…
Calculated in your browser for the summit coordinates (standard sunrise equation, Eastern Time). From a high summit with an open horizon, the sun appears a few minutes earlier and sets a few minutes later than the sea-level times shown here; the extra minutes are estimated from the summit's height.

63.8 miles of USDA Forest Service–managed trail: the full length of every USFS trail segment that comes within 2 miles of the summit (computed from USFS trail GIS data).
| Trail (USFS name) | Total length |
|---|---|
| Jewell | 3.3 mi |
| Six Husbands | 1.8 mi |
| Mt Clay Loop | 1.1 mi |
| Sphinx | 0.9 mi |
| Cabin-Cascades | 0.9 mi |
| Hincks | 0.6 mi |
| Mt Jefferson Loop | 0.6 mi |
| Edmands Col Cut-Off | 0.5 mi |
Lengths are each trail's full mapped length in USFS GIS data, not a summit route. Difficulty ratings are not published in this data, so we leave them out.
