Near Baseline Road and US 287, the Black Diamond mine was considered one of the best coal mines in northern Colorado. Employing some 100 workers, it was the last coal mine in the area to shut down operations in the mid-1950s. Two of the players from the 1936 team made major contributions to American athletics. The first, Byron “Whizzer” White (a future US Supreme Court justice) was the runner-up for the Heisman Trophy for football. He went on to play for the Pittsburgh Pirates, where he was named all-pro. He also played for the Detroit Lions. The second, Bauldie Moschetti, in 1964 founded the Boulder Collegians, a summer collegiate baseball team. He also served as the organization’s manager, general manager, recruiter, and primary sponsor. The Collegians won the National Baseball Congress World Series four times; more than seventy Collegians players made names for themselves in organized baseball. In appreciation for developing so many players, Major League Baseball awarded Moschetti a lifetime pass—allowing him entry into any big-league ball park free of charge.
