Submerged Mountains in the Straits

Stuart and I struggled to identify these mountains, but I believe now that at the far left, the small section in the midground is the far western tip of Gambier Island, the first peak on the left is Mt Wrottesley, the island in the center left partially hidden by haze is Anvil Island, the snowcapped peaks in the background are the Tantalus Range, the dark island in the center right is Bowyer Island, and the mountain behind Bowyer to the right is part of the mainland, but south of Tantalus.

Anyone with better information on the identifications is cordially invited to post a comment with corrections!
