Did You Know?
The depth of Crater Lake was first measured in 1886 with a simple sounding machine that consisted of a crank and a spool of piano wire. Those first measurements showed the lake to be 1,996 feet deep - not far off from the depth of 1,943 feet that was measured with high tech equipment in 2000!
