Glacier Once Visible From the White Pass and Yukon?

Has anyone seen an old - old photo taken along the White Pass and Yukon which shows the Laughton Glacier? The attached photo was taken a little east of WP&YR Tunnel No. 1. In the photo, about 1/4 down from the top, and immediately to the left of center, you see a gray patch. That gray patch is barren ground on which the Laughton Glacier once extended. The glacier has seriously receded since the early 1900's. I'm curious whether there is an old photo which shows the glacier on this spot.

They don't point this spot out on the train ride, because you can only see it from the cab or the rear car - not out of the side. The Laughton glacier is one of three glaciers near the White Pass and Yukon which has seriously receded since the early 1900's. The others are the Denver Glacier and the unnamed glacier at the head of the stream through Switchback Gulch. The Laughton Glacier was originally spelled "Lawton," named for a general killed in the Philippine-American War, until a spelling apparently with more snob appeal was adopted.
