IMG_7140 Ranger-Led Walk in Upper Geyser Basin, Yellowstone National Park
It's helpful to join a walk with ranger for deeper understanding about these thermal features. Scientists suspect the power of Giant Geyser is "stolen" by Grotto Geyser, as shown in this photo. So tourists may not see Giant Geyser eruption but Grotto Geyser eruption more frequently. However, things may change. Perhaps couple years later, they make a switch that Giant Geyser is more active and Grotto Geyser is dormant.
