entomologist jeffrey lockwood wanted to find out what
caused the extinction of the rocky mountain locusts.


scientists' work was treacherous
lockwood and his associate larry debrey made several
treacherous trips to the remote glaciers. finally, on their
fourth expedition, they discovered the rare specimens
they were looking for. their examination of the remains of
locusts buried in layers of glacier ice confirmed that locust
plagues were likely to have been an aspect of the prairies
for centuries before the pioneers came, and that the
extinction had indeed been sudden. but it brought them no
closer to solving the mystery.
