The terrain leading to Russell Peak, often via trails like the Lafayette Ridge Trail, is characterized by a 'roller-coaster' of continuous climbs and descents. You'll encounter gravel tracks and open, grassy slopes. Some sections can be fairly steep, especially the initial ascent, but it often moderates. Much of the route is exposed to the sun, though some shaded groves exist.
