Frost Jeep Trail #4W310

Area Status: Open
This area is Open

This 4WD/ATV trail in the Taneum Manastash Area goes from Forest Road 3100 to the Frost Mountain Lookout site.

This short out-and-back trail climbs steeply from road 3100 and ends at the Frost Mountain Lookout. Loose rocks toward the top make this trail challenging even in dry conditions. The view from the top is worth the challenge only if the trail is dry. Do not attempt to wheel or ride if the trail is wet. The descent is steep and treacherous.
