new pits are 300 feet apart. If all the test pits show sand and gravel, it is assumed that the entire area, 300 feet by 300 feet contains sand and gravel. Test pit E is excavated but no sand and gravel are found. This means the gravel deposit ends somewhere between B and E. It can be assumed the gravel material stops halfway, or in this case, 150
