The crusty white deposits around Vixen Geyser’s vent are most likely mineral deposits, specifically silica and sulfate minerals. These deposits form when the hot water and steam from the geyser contain dissolved minerals. As the water cools upon reaching the surface and evaporates, the minerals are left behind, creating the characteristic white, crusty formations.

Avoca Spring is a notable geothermal feature located in Biscuit Basin. It measures about 15 feet (4.5 meters) in diameter and reaches a depth of approximately 10 feet (3 meters). It's known for its vivid blue water and the surrounding mineral deposits that showcase a range of colors due to microbial life and mineral accumulation.

The gold-colored runoff at the Upper Geyser Basin in Yellowstone National Park is typically caused by thermophiles, heat-loving microorganisms that thrive in the hot, mineral-rich waters of the geothermal features. These microorganisms, particularly certain types of bacteria and archaea, produce pigments that give the runoff its striking colors. The gold or yellow color is often attributed to thermophilic bacteria like Thermocrinis or other species that can process sulfur or iron, creating vibrant hues in the runoff channels. These colorful runoffs are a hallmark of the park's geothermal activity.
