Abstract

These cones range in age from approximately 0.015 Myr to 1.09 Myr. Their degradational morphology displays trends that are closely related to cone age. 1) Crater-width/cone-width ratios decrease from 0.48 on the youngest cone to 0.21 on the oldest cone with a preserved crater. 2) Mean maximum side slopes (tan) decrease from 0.575 on the youngest cone to an average of 0.41. 3) Debris-apron-height/cone-height ratios increase from the youngest to the oldest cones. 4) Cone drainage evolves from irregularly spaced rills and gullies on the youngest cone to regularly spaced gullies and valleys on old cones. -from AuthorsUS Geological Survey, 345 Middlefield Rd, Menlo Park, California 94025, USA.
