Grand Prismatic Spring Coffee Mug
Steam rising from a hot spring like steam rising from your coffee! Grand Prismatic Spring is the largest and most brilliant of Yellowstone’s beautiful hot springs. Its large area stretches approximately 200 ft. (61m) across. The water temperature at 160 degrees Fahrenheit (70 C) ensures that the spring is mostly covered in steam. The hills in the background show the regrowth of forest from the significant forest fire that swept through this area of Yellowstone several years ago.
