trees. A second tornado (f1) touched down in Northglenn
and moved into Thornton damaging a group of self storage
garages... several vehicles... a wooden fence... several trees...
and the roof of an auto parts store. No injuries were
reported. The storms also caused minor street flooding
across northern and western sections of Metro Denver.
Rainfall totals ranged from 1 to 3 inches. Lightning
started a small fire at a home in northwest Denver. The
fire was confined to the front rooms and was quickly
extinguished. Snow plows were used to clear 2 to 4 inches
of pea to Marble size hail from a stretch of U.S. Highway
285 in Turkey Creek Canyon. Lightning felled a tree in

widespread flooding over the South Platte river basin.
Rainfall was heaviest in the foothills where 5 to 8
inches were measured over the 4 days. Heavy rainfall
west of Boulder flooded mining towns and damaged mining
properties. In the canyons above Boulder... railroads
and roads were washed out along with many bridges. The
floodwaters spread into central Boulder and covered a
wide area from University hill north to near Mapleton
hill to a maximum depth of 8 feet. Many houses were
swept away... and every bridge in Boulder was destroyed.
A few people... trapped in their homes by the floodwaters...
had to be rescued. However... the gradual rise of the flood
waters resulted in only one death. Boulder Creek spread to
a width of nearly one mile in The Pasture land to the east
of Boulder. Extensive flooding on Left Hand creek north
of Boulder washed away Railroad and wagon bridges. The
heavy cloudbursts caused flooding on Bear Creek... which
washed away bridges... Railroad tracks... and structures and
destroyed the canyon roadway. Morrison sustained the
heaviest flood damage on Bear Creek. In Denver... rainfall
totaled only 1.50 inches on the 30th and 31st... but the
heavy rainfall on upstream tributaries of the South Platte
river caused the river to rise as much as 10 feet above the
low water mark in the city... which caused some flooding of
pasture land downstream to a depth of 6 feet near Brighton.
