Perhaps most noteworthy, in April 2006 Doug Coombs died while trying to save a friend in the Couloir de Polichinelle.
The first recorded ascent of Middle Teton was by Albert R. Ellingwood on August 23, 1923, via Ellingwood Couloir on the south side of the peak.
Another popular route of ascent is via Andrews renne (Andrew's couloir), used in the first ascent of A. W. Andrews and party in 1899.
