## The Anglin Brothers: Swimmers in Cold Water
The question of whether Frank Morris and the Anglin brothers could have survived the bay depends significantly on what the Anglin brothers’ swimming ability actually was.
The family accounts — that the brothers routinely swam in Lake Michigan even when ice was present on the water — are impossible to verify independently at this distance. Family oral history about athletic feats tends toward enhancement. What can be assessed is what swimming in cold water requires physiologically and what training background the Anglins had.
The Anglin family’s migrations between Georgia, Florida, and Michigan for seasonal farm work gave the brothers an unusual range of environmental exposure for their era and economic circumstances. The Great Lakes in early summer are cold; the Michigan shoreline near cherry-growing country includes freshwater beaches where swimming was both possible and common for young men working the harvests. Whether the Anglins swam regularly enough to have developed cold-water tolerance is not documented beyond the family accounts.
Cold-water tolerance is real in a physiological sense. Regular exposure to cold water does condition the body’s response — trained cold-water swimmers show slower rates of core temperature loss and maintain cognitive and physical function longer than untrained swimmers in the same conditions. The specific level of conditioning the Anglins may have had from their farm work background is unknown.
What is relevant to the June 1962 escape is that the men were in a raft, not swimming. They were paddling, not immersed. The cold-water exposure risk was different from open-water swimming: a person in a raft is exposed to cold air and spray but not to continuous immersion. If the raft held up, the primary risk was not hypothermia from water immersion but the physical demands of paddling against currents in the dark.
