The tour descends imperceptibly in broad, sweeping curves through an uneven grazing region. Scab and lava rock ledges, brownish-black in color and very jagged, are frequently seen near clumps of bull pine. Gradually, the terrain alters; evergreens become scarcer; suddenly the timber line ends, and soon the rolling hills are gray with sagebrush. Herds of beef cattle graze on both sides of the road. During the spring months, the landscape is gayly colorful with sunflowers and lupine.
