Old Faithful Geyser, Yellowstone Park, as depicted in this picture is one of the typical mid-day eruptions when there is sufficient breeze to waft away from the 150-ft. water column its envelope of steam. These displays occur summer and winter at intervals of about 66 minutes. COPYRIGHT BY HAYNES INC., YELLOWSTONE PARK, WYOMING, U.S.A.
