Grindstone Lake is where I learned to swim many years ago. All the kids in my home town of Sandstone who wanted to were taken by a school bus during summer vacation each day for two weeks to this lake and Red Cross sponsored instructors taught us the basics. Also I went to a camp located on this lake. This is a panorama of seven photos merged with Lightroom.

Grindstone Lake is a large freshwater lake located in Dell Grove Township in east-central Minnesota approximately 6.5 miles (10.5 km) west of Sandstone, Minnesota. The lake is roughly oval shaped being approximately 2 miles (3.2 km) in length north to south and 0.5 miles (0.80 km) east to west, and a maximum depth of 153 feet (47 m). The lake has several small streams that drain the area wetlands and is considered the headwater for the Grindstone River. The lake's name is a translation from the Ojibwe zhiigwanaabikokaa-zaaga'igan (Lake abundant with grind stones). Sandstone taken from near the lake was used to make sharpening stones.
