Our Last Week in Yellowstone Area

Our last week in West Yellowstone we had another visit from friends. What a treat to be able to share the area with Jean and Joe. Along with other places we have already posted here, we visited Big Springs and The St. Anthony Sand Dunes, both in Idaho. Big Springs is the primary source of the Henrys Fork of the Snake River. It is one of the largest freshwater springs in North America with a daily flow of 120,000,000 gallons of water (yes, it's that many zeros) at 52 degrees Fahrenheit. Look at our previous post on Upper and Lower Mesa Falls, which are on Henrys Fork, to better see the volume of water.

At Big Springs, water runs out of the side hill. The water is very clear, which makes it easy to see the fish which are plentiful here.

It was impressive to see sand dunes in this part of the country near St. Anthony. They cover about 175 square miles with dunes ranging from 50 to 400 feet tall.

We also visited YNP with them which we always enjoy. Our trip that day took us on the lower loop where we visited many of the geothermal areas.
