Introduction
An older trachytic volcanic complex at Mason Spurr is overlain by a younger volcanic sequence consisting of a trachytic dome and tuff rings and numerous basanite and tephrite cinder cones. Several lava flows drape over the Mason Spurr bluffs, and may be less than 100,000 years old (LeMasurier and Thomson, 1990).---
