Public Demonstration Sunday, June 13
The 100-year old wooden Liberty Derrick will be operated at Quarry Park and Nature Preserve on Sunday, June 13, 2010 at 1 p.m., 2 p.m. & 3 p.m. for public viewing. Parking will be free that day.
Derricks were the main equipment for lifting huge blocks of granite from a quarry floor to a loading dock at the quarry surface. Stearns County Parks will operate the 10-ton capacity derrick to demonstrate the process to the public. It has been 50 years since a derrick was operated by a granite company at the site of Quarry Park and Nature Preserve. After painstaking restoration work and thousands of dollars of donations by benefactors, the derrick lives again.
Quarry Park is the home of "St. Cloud Red Granite," which was used for the columns in the former Carnegie Library in downtown St. Cloud. The columns are also on display at the derrick exhibit area. A four-ton block of St. Cloud Red Granite will be hoisted from the quarry floor starting at 1 p.m. Excellent viewing locations will be the observation areas along Quarries 17 and 18 just south of the parking lot. There will be opportunities to view the operation shack and talk to staff about quarrying. A seven-minute video of the "History of the Liberty Derrick, Lifting the Past into the Future" can be viewed on the county website at: http://www.co.stearns.mn.us
