Geo 730: May 29, Day 515: Quarry Wall

Looking up the back wall of the blueschist quarry in Bandon, you can see it's a windswept environment by the way the trees, probably shore pines, are feathered out. The invasive gorse in the foreground seems to compete especially well in disturbed soils with high precipitation, and cool, windy environments such as are found at Oregon's coast. I don't know if it has made its way inland to the valley, but Scotch broom seems to outcompete it in warmer and drier environments. As is the case all the time, the geologic and geographic setting plays a huge role in what living things fare well in an area, shaping both climate and soil.
