SHORT HISTORY
BOZ was established as a WWSSN station and operated efficiently until it encountered funding problems. It ceased operating
at the end of 1966; its equipment was finally removed in 1968 and sent to Missoula, Mont., a currently operating WWSSN station.
BZE was established in the mountains near the University to monitor avalanche activity.
BZM was located on the campus of the University and its operation contracted to the Physics Department by the USC&GS.
