20 Mar 12.  Those of you who keep track of this daily gibberish may recall that I sent an image of the Athabaska Glacier back on the 30th of January. Our visit to see it was in 1973, and it was most impressive. Like most of the glaciers in N. America, it is currently in a retreating phase, but as anyone who studies glaciers learns they advance and retreat and some do it with some apparent regularity. The link above has pictures from various times, and I thought the one from 2005 (sign says 1995) an interesting contrast to the image to its right as well as for what I'm sharing today. To say that the glacier we saw was a bit of an overwhelming experience would be a vast understatement, and perhaps I can put some perspective to that statement by explaining that the small dark blobs you see in the diagonal ice roadway in the lower right hand section of the photo are 22 passenger buses! The dark area in the lower left hand side of the image is also part of the glacier, being a portion of the glacier that has pushed rock up on top of itself as it moves forward. If you still have that image from the 30th (there is a copy of it on the blog) compare it with what I have included here. The 30th image is basically a magnified section of this image, encompassing a section from the middle and moving left. They are individual exposures, one taken to show the enormity of the glacier and another to give a more dramatic presentation. If you were to visit it today I'm rather certain that from this vantage point it wouldn't look much different , but if one were to stand at the toe I think it would drastically different. ISO would have been 100 as it was shot if Fujichrome but I have no exposure data available (memory just not all that good).
