Changes, rapid and slow, at the Learning Center
Does Justin go around mumbling about amphibians? Brandi about mycorrhizal fungi? Martine about the medicinal uses of Oregon grape?
Natural history projects are the last big curricular piece of the residency portion of the graduate program. I wonder how Cohort 9’s projects may be pervading their everyday life, since I know my research has seeped into mine. This is clearly shown in the following:
While cleaning the fridge last week I caught myself exclaiming “Ugh – catastrophic!†after opening a container that had clearly been inside too long. Even though the growth upon the leftovers had taken place in a uniformitarian fashion, the visual and nasal effect of this growth was clearly catastrophic on my senses.
You see, my natural history project has been on the geologic doctrines of catastrophism and uniformitarianism. The development of geology as a discipline is greatly comprised of these contrary fields of thought. Both are based upon observations of phenomena in the natural world and are  interpretations of those observations. Catastrophism is based upon sudden and often violent change; uniformitarianism is based upon change as a slow and gradual process.
The two creeks that bookend the Environmental Learning Center campus are wonderful examples of each of these two doctrines.
Sourdough Creek, fed by snowmelt, undergoes a wide array of flow through the year, ranging from being bone dry in late August to potentially torrential spring floods. Notice the lack of moss growth on the boulders and the boulders themselves as evidence of voluminous and rapid flow – smaller substrate particles have been flushed away. Even the “Texas dip†bridge crossing the creek is proof of the creek’s potential for change.
