First of all I would like to thank Luzerne County Park Director, Andy Gegaris,for permission to place this earth cache. This site is part of a 527-acrea Nature area and is popular among hikers,bikers,and cachers for its easily accessibility and beginner-level hiking environment.NATURAL HISTORY- More than 10,000 years ago the glaciers of the ice age were instrumental in the forming of the "tubs" or "potholes" as glacial melt waters produced large volumes of flowing water for many years, contributing to the formations in the different types of rock common to the area. Common geological rock classifications in the area are limestone,shale, and coal, but "The Tubs" are formed mainly of gritty sandstone. In the warm warm summers great cascades of melt water, bearing tons of gravel,sand, and boulders, spilled over the edge of the ice sheet or down through a crevasse within the glacier. Finding its way to the bedrock,the deluge of water swirled the abrasive material it carried around and around, hollowing out the bedrock into a series of potholes or tubs. Follow the rough path upstream along Wheelbarrow Run,which is the stream that runs through "The Tubs" and eventually meets up with the larger Laurel Run, both flows have cut gorges and canyons out of the surrounding landscapes. In one of the upper basins there is still a large boulder with which the water worked the stone. When the ice sheet finally withdrew to the north the volume of water decreased. the shape of the "Tubs" or "potholes" have remained essentially unchanged for thousands of years.
What you will see is a series of seven "potholes" or "tubs" formed from glacier melt water, the largest being at the top and the smallest at the bottom. Hence the name "The Seven Tubs".
