Missouri Caves & Karst Conservancy makes great strides in cleaning up Goodwin Pit
Practice proper disposal of wastes
There are numerous reasons to recycle materials and properly dispose of wastes and keeping trash out of our rivers and streams is certainly one. However making the connection between putting trash in a sinkhole and impacting the water quality of a special resource that many Missourians enjoy is not one that easily comes to mind. Enter Goodwin Pit.
Goodwin Pit, also known as Lanscaster Sink and located in Laclede County, has been used as an illicit dumping site for more than 50 years. The subject of a groundwater investigation by the Division of Geology and Land Survey, water traces using non-toxic fluorescent dye, have shown that the surface water that seeps through the trash in the sink emerges at Ha Ha Tonka Spring, flowing into Lake of the Ozarks.
Recently, the Missouri Caves and Karst Conservancy (MCKC) has made great strides in cleaning up Goodwin Pit. MCKC, working with other groups and volunteers have collected 25,860 lbs. of trash, 7.38+ tons of tires and 2500+ lbs. of metal, which was picked up for recycling, since the beginning of the project. The site is starting to look much better, but a good deal of work remains. This effort to clean up Goodwin Pit improves not only the landscape but will greatly improve the water quality of the karst system as well.

Cleanup is ongoing, thanks to the Missouri Caves & Karst Conservancy. Missouri Caves & Karst Conservancy photo.
Learn more about MCKC and see more photos. Upcoming workdays at Goodwin Pit are Saturday, Oct. 13, 2012 and Saturday and Sunday, Nov, 3 and 4, 2012.

Springs of Missouri — Hodgson Mill Spring
Hodgson Mill Spring
Hodgson Mill Spring is the site is one of Missouri’s most photogenic mills. Its picture has appeared on postcards sold throughout the state for decades and has been used to promote tourism in the Missouri Ozarks. The mill was first constructed in 1861 and was subsequently rebuilt after being destroyed by fired. The spring and mill are on Highway 181 in Ozark County.
The spring outlet cannot be easily seen because the mill was built over it. The opening is a join in the dolomite and sandstone enlarged by solution and is situated at the base of a high bluff. After leaving the outlet, the water enters a circular pool in front of the mill and passes over a dam and into the spring branch. About 600 feet down the branch, the stream enters Bryant Creek. Mill Spring flows about 20 to 28 million gallons of water daily and is one of Missouri’s largest springs.
