After a dormant interval of 2 years and 139 days, on this snowy Thursday one of Yellowstone’s most powerful geysers awoke and put on a show for the few Yellowstone visitors in the Upper Geyser Basin. Giantess erupts in spurts of various durations interspersed with roaring steam periods. It may go 200 feet high above Geyser Hill but gives no warning before it starts.
The last eruption of Giantess was on September 13, 2011. It had erupted two or three times per year for the quarter century or so before that.
I got lucky only once in the dozens of times I’ve been in the park. That was on September 5, 2001—note the proximity to 9/11—and our flight home from the park touched down in Rhode Island on the evening of September 10! My friend and map-maker Linton Brown was able to shoot the picture now gracing page 98 of Yellowstone Treasures.
