Abyss Pool in Yellowstone National Park may not get as much press as its cousin Old Faithful, but it’s one of the park’s most dazzling treasures. Read on to learn more about visiting this unique spot.
In 1883, a park visitors described this pool as "a great, pure, sparkling sapphire rippling with heat." And that’s pretty spot-on.
You wouldn’t know it now, but Abyss Pool was once an active geyser. Between December 1991 and June 1992, it exploded several times day with plumes of hot water that reached 30-80 feet in the air.
