Shaped somewhat like a morning glory, this pool once was a deep blue, but the color is no longer as striking due to tourists dropping coins and other debris into the hole. To reach the pool, follow the boardwalk past Geyser Hill Loop and stately Castle Geyser, which has the biggest cone in Yellowstone. Morning Glory is the inspiration for popular children's author Jan Brett's story Hedgie Blasts Off, in which a hedgehog goes to another planet to unclog a geyser
damaged by space tourists' debris.

Visit the park and don't miss the Morning Glory Pool. I used to live near Yellowstone Park at Bozeman; in fact, I graduated from high school in Bozeman in 1966 and with a master's in soil science from MSU Bozeman in 1979. I no longer live in Montana, but believe I’ve still got one of the finest photos of the Morning Glory Pool taken in 1965 before the pollution and color changes and when the full circle walkway was still in place and you could see
reflections of people in the pool. When I first uploaded it, it was getting 300 views per day, but I took it down. It’s now back up, take a look, please. I’d worked hard on a ranch near Glacier all summer for $75, spent half on a then old camera, the first 35mm SLR made. This was a 35mm slide, computer scanned about 2006.
