(A) Raw data from CMP survey at Government Hill. Travel times from the reflectors vary hyperbolically as the
antenna separation increases, whereas direct arrivals through the air and ground vary in a linear fashion.
(B) Velocity stack section calculated from CM P data in (A). An average velocity of 0. 12 m/ns (arrow)
is estimated for signals traveling between the surface and the reflection at 200 nsec (dashed line). ns, nsec.
