Green Mountain joins the list of several “Green Mountains” in Idaho, a few of which are on the website. Ironically, this Green Mountain is open rock terrain on its summit ridge crest. There is nothing “green” about its summit. During archery season, you are likely to encounter deer hunters along FSR-342. USGS Snowdrift Mountain
South Ridge, Class 2
From the signed turnoff on US-30 in the center of the bustling metropolis of Georgetown, ID, turn east onto Georgetown Canyon Road (which is called Stringtown Road within the city limits). Drive up the road to a junction at 2.3 miles (LEFT is CR-1095/Left Hand Fork Road; STRAIGHT is Georgetown Canyon Road/FSR-102). Go straight; the road changes from paved to gravel here. At 3.5 miles, you enter the Caribou National Forest. At 11.7 miles, the road crests at Georgetown Saddle and enters Caribou County. Park at this saddle at the junction with FSR-342 to the left/west. The elevation here is 8,050 feet.
From the junction of FSR-102 and FSR-342 at Georgetown Saddle, hike up FSR-342 in a northwesterly direction heading toward the south end of the south ridge of Green Mountain. FSR-342 begins as a jeep road but soon reaches a large parking area, where it turns into an ATV trail. In 0.7 miles, you reach an unmarked road junction at a minor saddle. FSR-342 turns sharply right/north here. Leave the road here (8,175 feet) and follow an old ATV road northwest briefly. The old ATV road quickly morphs into a trail and then into an old road. Follow the trail and old road westward to reach the base of the south ridge. The old road ends here.
This is open terrain so it is easy to see the south ridge above and to the right/north. Climb north up onto the south ridge (with some thick brush initially) then follow the right/east side of the mostly-open ridge in easy, open veg then broken rock. It is just over ½ mile from the base of the south ridge to the summit of Green Mountain. The summit is merely the highest bump on the rocky ridge crest. The USGS BM is located in a ground boulder just below the high point on the east side of the ridge crest. You’re likely to miss it if you don’t either know where to look for it or if you don’t descend the east face (which I did).
East Face, Class 2+
Same as for the south ridge.
From the summit, descend the steep east face on steep scrub (initially) then a rocky gully (which almost looks like an old jeep road) then through a thick forest of pines and aspens to reach FSR-342. Follow FSR-342 right/south back to the unmarked road junction at a minor saddle. Be sure to go left/east at this junction in order to stay on FSR-342 and return to its junction with FSR-102 at Georgetown Saddle.
