Coverage:

Median Latitude: 39.866671 * Median Longitude: 175.003571 * South-bound Latitude: 39.500000 * West-bound Longitude: 174.100000 * North-bound Latitude: 40.100000 * East-bound Longitude: 175.250000

Comment:

Age is fission track age, calculated using the zeta calibration method. Positions are estimated from map
