Salvage diver, adventurer, MIT grad, Milwaukee born and raised Max Gene Nohl and a close knit team at DESCO (a Milwaukee based underwater diving equipment manufacturing company he co-founded) created the first self contained underwater breathing apparatus(SCUBA) in the form of a lightweight heliox diving suit fitted with tanks and a sealed wide view diving helmet. In the winter of 1937, he tested the suit using a newly created helium/oxygen breathing mixture in a record breaking 420 foot dive to the bottom of Lake Michigan. The helium/oxygen mixture idea was developed with fellow DESCO employee Dr. Edgar End of the Marquette School of Medicine. In one bold move, the diving world took a quantum leap forward and Milwaukee was ground zero. "The Deepest Dive" made international news and it's young diver was an international celebrity. This was not the first dive using his new equipment. The previous summer had brought him to the pyramids of Rock Lake in Lake Mills, Wisconsin.
For years, fishermen and pleasure boaters had reported seeing unusual underwater structures in Rock Lake. The structures were first described as "pyramidal" in newspaper articles during a wave of pyramid mania that swept the Badger State in the early 1900’s. Max Nohl could not resist. He made a series of test dives in the late summer. Underwater conditions at Rock Lake were difficult - at times murky, suddenly clear, then - in the blink of an eye - black with silt. Toward the end of his last dive, he came across a tall pyramid-like structure made of densely fitted small rocks. To the eye of this trained engineer, it had the hallmarks of being man made. Max wanted to return to the lake and dive more extensively, but it wasn't to be. Years later he and his wife died in a horrific car accident, a high speed head on crash that also took the life of soul singer Jesse Belvin. The undersea structures of Rock Lake remain a mystery and are the subject of ongoing research. Some believe them to be the remains of a
