This trip was unlike any we had as a family. Most summers, we camped in state or national parks, as do many families of teachers—public servants using the public parks. We visited nearly every California State Park, our particular favorites including Calaveras, Donner, Grover, Big Basin, and Big Sur. We camped in national forests when we could not get the spot we wanted in a national park, e.g. Yosemite or Grand Canyon or Sequoia. We traveled and camped from June through September, when we started back to school.
Our children began their camping adventures when they were merely weeks old. Dale’s down jacket served as a sleeping bag for a 6 week old and nursing was a snap in the middle of the night. No bottles to boil, no formula to mix—made for an easy vacation. By the time our girls were in high school, they could put up a tent in record time, which was often serious family competition. Cooking on the Coleman stove was a creative art, which we mastered. Therefore, this particular summer, while I was studying, testing, and recording, my family was fishing, swimming, and relaxing by the Yellowstone River.
University of Montana offered this field study. As with any graduate level course, required reading was assigned ahead of time. I ordered the requisite texts, and weeks out, began the reading assignments. At the start of class was a preliminary test, so I plunged into the mandatory reading while we drove to Yellowstone. This geology course covered scientific testing of some of 10,000 hot spots, such as geysers, fumaroles, and mud pots. By casting a fishing line, attached with a thermometer or water-collecting instruments, into geyser basins, researchers gathered data without endangering lives. Every season, occasional tourists and random pets fall prey to geysers or fumaroles by straying too far from the boarded walkways and falling into the boiling waters—despite the posted warnings, newspaper accounts, and cautionary words of rangers. Some locals keep mortality rates on visitors searching for that perfect picture, or unleashed, wandering dogs that lose their lives to the hot springs, or bison who pummel them.
For our research, we were nowhere near the boarded walkways or civilization. We collected data in the Norris Basin, the most seismically active area of the park, and therefore the most dangerous. We brought along biological testing kits and medical supplies and a park ranger, who carried his walkie-talkie, our only link to the outside world and help, should we need it. Recording data all day long in the hot summer sun, while dodging flies the size of small bats and mosquitoes the size of small birds, yet this was my idea of an exciting vacation. I love outdoor biology—my true calling—and I felt in my element as I crouched in the dust and dirt, inhaling fumes of sulfur, and batting away at the constant attack by insects. And, I was ready to pack up and move to Yellowstone permanently.
One particular trek skirted a blackened sulfur pool, a tar-y-blackness that I had seen before, but always in a lab and never in nature. The pool was blacker than the blackest charcoal I ever made in many a science lab, pouring sulfuric acid over sugar, watching as the bubbling mass oozed out of the beaker, while students ooh’d and aah’d and held their noses. Here, we stopped to run the spectrophotometer and assess the compounds present in nearby streams and fumaroles. We ran tests to measure biologic variations, to assess seismic changes in the basin—to determine the rapid or slow but constant evolution that Yellowstone is famous for. The dramatic variations in color are due to the differences in pH and temperature and we tested nearly every color in the spectrum.
On the last day of our vacation, my exhausted family bedded down at nightfall, while I studied by flashlight for my final exam. Sammy saw a bear, the one animal she had searched for, and which earned her Yellowstone National Park Junior Ranger patch, while I earned my one-graduate unit that moved me to the farthest column on the pay scale.
