Corporation Park is a traditional Victorian park in Blackburn, Lancashire, England. It was landscaped by William Henderson and opened in 1857. Corporation Park is regarded as the main formal park in Blackburn and is used mainly by local people for general recreation, walking and dog walking, as well as for its tennis, bowling and football facilities. Has been described in the victorian times as the lungs of Blackburn.
The park area contains large reserves of Millstone Grit and was previously a quarry called Park Delph. An ideal building material, the millstone grit was used for building the majority of the cotton mills and churches in Blackburn.One of the park's two lakes was created in 1772 as the town's water supply, Pemberton Clough. A system of wooden piping carried the water to the town until the installation of the mains water in 1847. The smaller lake was known as 'the can' as citizens drew water from it using cans. The reservoir was consequently named 'big can'.Both are on the County Sites and Monuments Record for Lancashire.
The earthcache is evidence of A glacial erratic is a piece of rock that differs from the size and type of rock native to the area in which it rests. "Erratics" take their name from the Latin word errare, and are carried by glacial ice, often over distances of hundreds of kilometres. Erratics can range in size from pebbles to large boulders such as Big Rock (15,000 tonnes or 17,000 short tons) in Alberta.
Glacial ice entrains debris of varying sizes from small particles to extremely large masses of rock. This debris is transported to the coast by glacier ice and released during the production, drift and melting of icebergs. The rate of debris release by ice depends upon the size of the ice mass in which it is carried as well as the temperature of the ocean through which the ice floe passes
Erratics provide an important tool in characterizing the directions of glacier flows, which are routinely reconstructed used on a combination of moraines, eskers, drumlins, meltwater channels, and similar data. Erratic distributions and glacial till properties allow for identification of the source rock from which they derive, which confirms the flow direction, particularly when the erratic source outcrop is unique to a limited locality. Erratic materials may be transported by multiple glacier flows prior to their deposition, which can complicate the reconstruction of the glacial flow
In order to log this earthcache please email the following information found at the above co ordinates. You can log it at the time but if no email has been sent after a couple of weeks I will delete the log
1) Where did the rock come from (originally)
2) Estimate the height, width and length of the rock.
3) Describe the texture of the rock and why do you think it has this texture.
4) What is the number on the Discovery Plaque for this feature
It would be nice if you could post a photo of either yourself or your GPS at the location ( try not to give anything away which would allow guessesย for the answers).
