We love the West Thumb Geyser Basin in Yellowstone National Park because it sits right on the shore of Yellowstone Lake! In fact, some of the geysers are actually IN Yellowstone Lake, such as Fishing Cone, Big Cone and Lakeshore Geyser. In the spring, when the water level is at its highest, many of these geysers are submerged under water. Then as the lake level lowers throughout the summer, these geysers surface above the water level for all to see.
