USFS trailhead used for comparison
Drakes Brook/Sandwich Mtn Trailhead: 1,417 ft (2.7 mi from summit, straight line)
Elevation difference
2,550 ft from Drakes Brook/Sandwich Mtn 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: 944 ft/mi — Moderate
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.
