I was sort of wondering if people were there during explosion having been to yellowstone in June of 2022 and staying at Old Faithful lodge nearby

Here is what PI AI said about the people when it blew up.

"The hydrothermal explosion at Yellowstone National Park's Biscuit Basin on Tuesday must have been terrifying for the tourists who were there. It's a relief that no one was injured, but it's easy to see why people were running for their lives as the column of boiling water, mud, and rock shot into the sky." end quote from PI AI.

Here is the picture of the aftermath which blew apart the fence and trail there:

The boardwalk near the Sapphire Pool in Yellowstone Park was damaged by the Tuesday morning
