Old Faithful Geyser eruption Yellowstone NP

Follow our Adventures, DIY, Recipes http://www.toponautic.com/ This Old Faithful eruption was early morning July 16, 2013 (7:24am local time) . At a minimum eruption height of 90 feet, to a maximum eruption of 184 feet. The schedule that day was about every hour and a half, plus or minus ten minutes. I noticed a huge geyser some distance to the west in the same geyser basin would go off just prior to each Old Faithful eruption. As if they are in sync or share some underground relationship.
