A
River Dammed
The
Gros Ventre slide may been started by heavy prolonged rainfall. Some 50
million cubic yards of sandstone, limestone, shale,
about
one mile long, 2000 feet wide and several hundred feet deep in places,
plunged down and formed a dam 225 feet high and
nearly
half a mile wide across the Gros Ventre River. A lake was created above
the dam.
For
almost two years this earth dam held; then on May 18, 1927, part of the dam
gave way and a wall of water mud and rock
flowed
down the canyon destroying valuable property. Ranch lands were ruined
by mud and rubble and the town of Kelly,
three
and one-half miles downstream was practically wiped out. Six persons
drowned.
