YOU MUST SOLVE THE PUZZLE TO FIND THE CACHE
On February 3, 1959, American rock and roll musicians Buddy Holly, Ritchie Valens, and "The Big Bopper" J. P. Richardson were all killed in a plane crash near Clear Lake, Iowa, together with pilot Roger Peterson. The event became known as "The Day the Music Died" after singer-songwriter Don McLean referred to it as such in his 1971 song "American Pie".
There is a memorial at the crash site accessible from the trail head next to the Buddy Holly Glasses monument located about five miles north-northwest of the Clear Lake Airport near the intersection of Gull Avenue and 315th St.
