Rounding out our YNP experience we headed out late morning to Mammoth Springs at the northern edge of the park. On the way up we checked out Roaring Mountain. Lots of thermal vents of various kinds. Years ago when the mountain was more active the roar could be heard four miles away. That’s impressive.
Also impressive is Mammoth Hot Springs. The terracing created by flows of sulfuric stuff through the rhyolite is unusually pretty. It’s amazing how hot water and gas can create so many different variations. Extremely interesting and another glimpse into the handiwork of our creative, powerful God.
We had lunch—ice cream—at the grill in the village of MHS and then drove a backroad up to the north entrance of YNP. Good call because we saw elk and pronghorn grazing on the hillside. I think pronghorns are the coolest looking animals with their colorful markings and fluffy white butts. But that’s me…

On the return trip to West Yell we stopped into Norris Geyser Basin, which was slammed earlier in the day, and walked around the boardwalk to see its version of hot water coming up through the ground. I still wasn’t getting tired of the fumaroles, cauldrons and springs. But we forewent the loop around the back basin in favor of a beer back in camp.
The Madison River elk family greeted us again on the final leg into West Yell; this time they were just hanging on the far side of the river with the big boy looking over his harem. Yep, another great day in our great nation’s first and greatest national park! Next up: The Grand Tetons!
