Glacial erratic boulders atop Olmsted Point, with the massive granite monoliths Half Dome and Clouds Rest in the background. Erratics are huge boulders left behind by the passing of glaciers which carved the granite surroundings into their present-day form. When the glaciers melt, any boulders and other geologic material that it was carrying are left in place, sometimes many miles from their original location.

Daisy Geyser erupting with visitors visible in the distance.. Daisy Geyser, a cone-type geyser that shoots out of the ground diagonally, is predictable with intervals ranging from 120 to over 200 minutes. It reaches heights of 75 feet, lasts 3 to 4 minutes and rarely erupts in concert with nearby Splendid Geyser. Upper Geyser Basin.
Location: Upper Geyser Basin, Yellowstone National Park, Wyoming

Castle Geyser erupts with the colorful bacteria mats of Tortoise Shell Spring in the foreground. Castle Geyser reaches 60 to 90 feet in height and lasts 20 minutes. While Castle Geyser has a 12 foot sinter cone that took 5,000 to 15,000 years to form, it is in fact situated atop geyserite terraces that themselves may have taken 200,000 years to form, making it likely the oldest active geyser in the park. Upper Geyser Basin.

Devil's Postpile, a spectacular example of columnar basalt. Once molten and under great pressure underground, the lava that makes up Devil's Postpile cooled evenly and slowly, contracting and fracturing into polygonal-sided columns. The age of the formation is estimated between 100 and 700 thousand years old. Sometime after the basalt columns formed, a glacier passed over the formation, cutting and polishing the tops of the columns. The columns have from three to seven sides, varying because of differences in how quickly portions of the lava cooled.
