Harry Fielding Reid
Cleveland, O. Feb 19, 1891
My dear Prof. Muir,
I have been at work all the winter, giving all the time I could to preparing a report of my last summers’ observations. My map is finished, my photographs are now being printed and I am writing our my report, which I hope will soon be completed. Prof. Wright has sent me a photograph which he took of the ice front in 1886, from a point some two thousand feet above it. It shows the great
central point, he has figured in his map, projecting about a quarter mile beyond the sides; so we shall have to concede considerable changes in the form of the ice front; in fact after you left us last summer, the ice of the eastern part of the front fell away so rapidly that it produced a bay about a quarter mile deep. But what is more interesting still; on comparing Prof. Wrights’ photograph with my map, I find that the ice-front has receded about
a thousand yards in the last four years. This brings up another point: Capt. [Carroll?] made several soundings last summer. I unfortunately failed to record them; but as I remember, the first was some two or three hundred yards from the ice and showed a depth of 680 ft. The second was quite near the ice and showed 720 ft. Now as all this space was covered by the ice four years ago, this difference of level, 40 ft, could not
could not be caused by sedimentary deposit since then; therefore there must be a depression in the bed of the glacier, which would be a lake basin if above the level of the sea. This lake basin, however, may not be in solid rock, but may be in glacial till, & present a rising front just as the present deposits under the [wings?] of the glacier. If you have or can get me the actual soundings and just how far from the ice front they were made, I shall be greatly obliged. I shall soon be able to send you some photographs.
Yours truly sincerely
Harry Fielding Reid.
