"In August 2025, we visited the Hot Springs State Park in Thermopolis, Wyoming. The hot springs are adjacent to the Bighorn River, and they claim to be the world's largest mineral hot springs. The mineral rock formations are beautiful and colorful to see. The nearby mountain has "World's Largest Mineral Hot Spring" painted on it. We would like to return to Hot Springs State Park and spend more time there."
John Cutler
