A thermo-erosion gully has been monitored in the valley of glacier C-79 on Bylot Island since 1999. The main channel of the gully reached 390 m in length a few months after its initiation and grew between 38 and 50 m/year over the following decade, for an overall approximated average of 75 m/year.

In 2009, the total gully length and area, including the main and relict channels, were 2500 m and 25 000 m 2 , respectively.
