Mammoth Spring state park is in Arkansas just across the state line from Thayer, Missouri. This picture is of a little outlet located next to the spring. Mammoth Spring boasts the 10th largest natural spring in the world.
This is another view of an outlet from the spring. There are two such outlets. The spring is indicated by the "pond" from which the water flows. Over 9 million gallons of water is produced from the spring every hour.
The town of Mammoth spring was a hub of freight and passenger trains in the late 1800's. This picture is of the depot from 1888 which is now a museum. The train tracks are just on the other side of the building which carry several trains a day even now, although they no longer stop at the depot!
Grand Gulf state park is near Thayer, Missouri and is often called the "little grand canyon of Missouri". It was formed by the collapse of an underground water way, forming a rather large crater. This is a view from one of the platforms along the rim.
There are several hiking trails that take you around the gulf with plenty of God's natural beauty around. A very enjoyable day together and it was all free.
