Sinkhole 2010 Guatemala City sinkhole formed suddenly in May of that year; torrential rains from Tropical Storm Agatha and a bad drainage system were blamed for its creation. It swallowed a three-story building and a house; it measured approximately wide and deep. A similar hole had formed nearby in February 2007. This large vertical hole is not a true sinkhole, as it did not form via the dissolution of limestone, dolomite, marble, or any other water-soluble rock. Guatemala City is not underlain by any carbonate rock; instead, thick deposits of volcanic ash, unwelded ash flow tuffs, and other pyroclastic debris underlie
Pipe Creek Sinkhole Mammalian finds include an early rhinoceros ("Teleoceras", possibly from the Miocene epoch), canids, peccaries and short-faced bear. Backed by a grant from the National Science Foundation, researchers from the Indiana State Museum and several universities substantially completed field work at the sinkhole in the summer of 2004, but there was about one weeklong dig a year from 2005 to 2011. What probably was the last work at the site took place in 2014, with scientists and volunteers screening soil previously removed from the sinkhole.
