until the morning of the 8th. Very high rates of
rainfall occurred on the 6th and 7th with the greatest
intensities in a band along the foothills from about 25
miles southwest of Denver northward to Estes Park. Storm
totals by both official and unofficial measurements
exceeded 10 inches over much of this area and were over 12
inches in some localities. Heavy snow fell in the higher
mountains and in the foothills later in the period. The
saturation of the soil resulted in numerous rock and land
slides... and the heavy run-off caused severe damage along
many streams and flooding on the South Platte river. Many
foothill communities were isolated as highways were blocked
and communications disrupted. Roads were severely damaged
over a wide area... and a large number of bridges washed out.

Rocks. A building in Georgetown collapsed from the weight
of heavy wet snow. In Boulder... a man drowned when caught
