| Abstract | Preliminary results from a multiple-traverse radar survey across an ice cap situated on top of Hoodoo Mountain, a Quaternary subglacial stratovolcano in northwestern British Columbia are presented. The
project defined the shape of the ice sheet and mapped the subglacial summit region of the volcano. Four traverses, using low-frequency ice radar and higher frequency ground-penetrating radar units, provided traces of the ice base as well as shallow,
finer scale, internal reflectors. GPS was used to locate survey lines and individual radar traces were time tagged to position.
The ice cap has a relatively even thickness (120-150 m) across the summit region, with no evidence of a deep crater or
caldera beneath. The minimum volume of ice is estimated at 3.2 km3. To more accurately gauge the potential for significant jökulhlaups at Hoodoo Mountain, additional work is necessary to define the nature and size of subglacial catchments basins.
