Project: Examining changes in lava flow texture (frothy to dense) in Highway flow at Crater's of the Moon. The goal is to understand the implications frothy and dense textures have regarding the rheology and morphology of the flow.
Project: Looks at patterns in the tephra deposit from Kings Bowl to determine eruption pattern.
We will do this by collecting tephra from various sites around King's Bowl.
We will then sieve the samples collected and examine differences in clast sizes. We will also look at the composition of the samples at each site, looking for what percent is lithic and what percent is eolian dust.
We will use information discovered to determine eruption patterns.
Goals: Tephra section of KB eruption modeling paper and Rocky Mountain GSA talk!
