This map area is composed of recent lava flows, less than 10,000 years old. It extends from the base of the mountain at about 3500 feet elevation to timberline at about 8,000 feet elevation. It is essentially all barren, rugged lava flow.

Lava Park is within Mount Shasta's "rain shadow". Very little vegetation is able to survive on the dry, rocky slopes. Scattered western juniper and mountain mahogany can be found in this area.

The most prominent feature in this map area is the terminus of the flows as seen from Highway 97. The flows are sparsely vegetated with mountain mahogany and greenleaf manzanita.
