Dean Channel on the left, Burke Channel on the right. |
I didn't know the location of this challenge when I posted it, but having seen it from the air, I knew it was between Anchorage and Seattle, that it was south of a more-or-less north-south-trending strait, and that it was much closer to Seattle than Anchorage and probably south of SE Alaska. This general knowledge gave me an advantage over anyone else trying to discover the location. I homed in on the location and found most of the names of the fjords and mountains on Google Earth (in labeled photos), but wasn't sure if the names were correct, so checked them on Wikipedia and GeoBC.
Google Earth image almost identical to my first photo. Dean Channel is on the left; Burke Channel is on the right. |
A photo zoomed in on Burke Channel. |
Google Earth image with Burke Channel centered, similar to the previous photo. |
Zoomed in photo with the mountain in question in the distance. |
Google Earth view, with the North Bentinck Arm of Burke Channel on the left and the South Bentinck Arm heading southward to the right. |
Google Earth image: Thunder Mountain is the highest peak in the center; Tzeetsaytsul Peak is the next highest peak to the left (north). |
Google Earth view of Tzeetsaytsul Glacier on the east side of Tzeetsaytsul Peak and Thunder Mountain; north is to the right. |

Interesting! I didn't think to look for an online source of BC Geographical names. Instead, I sought out a KML file of BC topographic maps (http://geobc.gov.bc.ca/base-mapping/imagery/topographic.html) that I could overlay in Google Earth, where I pulled up the relevant topo maps as PDF files.
Well, you found the same basic site (geobc.gov) -- I happened on a link to the geographical names on Wikipedia.
