“A wonderful short trail through beautiful springs and interesting small geysers.”— Tom Carter
Just past the junction with the loop trail, as it joins from the right, Jewel Geyser is reached. It is named for the lovely beads of sinter around its vent. A bit further on the left is Shell Geyser. Its fun to guess the names of features or to look for the namers reasoning. Can you see the resemblance to a yellow clam shell? Next are Silver Globe Spring and Avoca Spring.
At the trail junction stay right and loop around the boardwalk. There is also more subtle activity in geyser basins. Look closely, you may discover a small dark-colored shore fly. A "vegetarian," the fly feeds on the algae and bacteria that thrive here. With luck, you may also spot a wolf spider, tiger beetle, or a bird known as a killdeer. These are the "carnivores" of the basin. They prey on shore flies and their orange-colored eggs for nourishment. Many of these life forms are so perfectly adapted to the basin, they can be found in no other environment.
