| Introduction
"Quicksand River"
The
Lewis & Clark Journals
"Capt
Lewis and myself walked up this river about 1 1/2 miles to examine this
river which we found to be verry Considerable Stream Dischargeing and to
my astonishment found the bottom a quick sand,and impassable, ...A
Mountain which we suppose to be Mt. Hood is S. 85 degrees E about 47 miles
distant from the mouth of quicksand river This mtn. is covered with
Snow and in the range of mountains which we have passed through and is
of a Conical form but rugid."
Captain
William Clark was very impressed with the Sandy River Delta. He recorded
over three pages of observations where the Sandy River flows into the Columbia
River. Captain Clark named the Sandy River "Quicksand River", because when
he walking on the delta, he sank up to his waist. He thought it was
quicksand, but actually it was volcanic ash and silt from the eruption
of Mount Hood in the late 1700's.
