Morris Mine
The seam at Morris Mine was between 900 and 920. Both Morris and Montour No. 1 were located on the north side of the Cross Creek Syncline, which is why the coal was deeper. Surface elevation at Morris was about 1080, making it around 160 to 180 feet deep. If you assume the slope entry was at an angle of 30 degrees, that would make it around 360 feet long. It was probably less steep than 30 degrees.
