Today is the last day for access via over-snow vehicles to the interior of Yellowstone hence ending another winter season. That said, depending how you define winter, winter weather is still possible across the region for quite a while longer. Plowing is underway in Yellowstone and roads will being opening around the third week of April. This image was taken this winter at Midway Geyser Basin. The view across the layered snow shows steam rising from Excelsior Geyser. Excelsior Geyser supposedly had eruptions 300 feet high by 300 feet wide but it’s believed those powerful eruptions damaged the plumbing system. Today, it still discharges around 4,000 to 5,000 gallons of water per minute into the Firehole River.
