I spent a summer working as a geological field assistant for Amoco Minerals Company in an isolated area of the Rocky Mountains in Colorado. Working at well over 11,000', I helped build a several-mile trail up a steep, sulfur-rich mountainside. Then I assisted in the construction of the base camp, including setting up tents, plumbing facilities, appliances and other equipment. Once that was completed, we constructed trails to drill rigs located up to two miles from the base camp. After that, my work duties consisted of hauling all the core samples produced by the drill rigs to the base camp; cleaning, measuring and splitting the core samples; and working as camp guard when the drillers and geologists went on vacation.
