Although these are the
most current estimations obtainable, they could only be approximated
based on the mapped extent of the deposits. Additionally, given that
the isopach maps only include thicknesses N2 m, simulated deposit
thicknesses b2 mcould not be calibrated. Similarly, the PDC calibrations
were constrained by the most distal exposure known of Battleship Rock
Ignimbrite, although it could have potentially had a farther runout
length than what is currently exposed.
