Introduction:

For the third trip, we traveled to the North Fork of the Teanaway on 05/22/2014. We slowly made our way up Iron Peak and witnessed a transition from normal to serpentine soil types. We also, consequently, witnessed a transition in trees and under story composition.

• Role of elevation, aspect and slope
• Role of parent material, particularly serpentine bedrock and soils
• Depth and distribution of snow - processes leading to and then affect of depth and distribution on vegetation
• Meadows - understand location and processes leading to ..
• Disturbances such as insects, pathogens, fire and avalanches. Identify evidence of at least one example of each.
• Mixture of westside and eastside species - who, what, where?
