Matanuska Glacier, Alaska
Yesterday we looked at the samples from our fifth dye test. In this test we went up the glacier to the same moulin with which we conducted our unsuccessful conductivity experiments. We sampled from M-1 and Mega Vent once again. The results were inconclusive but encouraging. There was a slight trace of dye detected in one of the vents. We believe this to be a good indication that a connection exists to this moulin as well. In each of our previous dye tests we always had zero concentration readings before and after the rapid rise and subsequent fall in dye concentration. To see any measurable amount of fluorescence is taken as a good sign. Our feeling is that the dye has been diluted too much with the greater distance that it must now travel. Tomorrow we will repeat the same experiment but with triple the amount of dye previously used.
Bob Bigl was back on the ice boring new holes again today and I once again went along to watch and help whenever possible. Unlike yesterday, todayís weather was cloudy and cold all day long. The chill was starting to get to me worse than yesterday. At about 1:00 when the drilling was well underway I decided to hike up glacier to warm up. I was certain that there was a spot on the glacier where I would be able to look around 360 degrees and be above it all. It appeared that such a place existed when I looked at the glacier from the highway a few miles away. I decided it would be easier to hike on the moraine than the ice. Itís amazing how different the temperature is on the dark moraines compared to the white ice. It wasnít long before I had peeled off my fleece jacket and another shirt. The hiking was sort of like walking through a series of small mountains. I was constantly having to look far ahead to see if my progress might be stopped by a crevasse or ice cliff. I kept heading toward the highest mound of ice and rock that was in sight at any given time. Along the way I climbed up a couple to what I thought would be the high point I was looking for only to spot one still farther ahead that was even higher. I wasnít sure how long this would go on but I continued nonetheless.
Finally I ascended a series of ridges that eventually led me to the magic spot that I had hoped would really exist. I had been hiking toward this point for more than an hour by now but it was certainly well worth the effort. As I reached the top and looked over the other side I quickly noticed an enormous moulin dropping immediately beneath my feet like a huge crater. I noticed a spiraling ridge that went down to the bottom and I followed it to an ice cave into which all the water was flowing in. The sound of tiny water flows all around seemed amplified by the surrounding walls. Looking up and all around toward the sky was sort of eerie from deep inside this hole.
It is very difficult to get a sense of scale out there when everything is so big. The terminus of the glacier bends around Mt. Wickersham which rises nearly 6000 feet up from the glacier surface. It doesnít seem to be such a big mountain because of so many others that tower much higher. The glacier definitely looks big as you approach it and even as you walk around on it. But it looked absolutely huge from my tiny rock summit today. The mountains to either side of me seemed so distant. The parking lot back at the terminus was so small now as to be unrecognizable. The drill site looked like a tiny speck. I could tell that it would be a very long walk to continue up the glacier just to get around the bend of Mt. Wickersham, one that would require at least a backpack and overnight provisions.
On my return hike I came upon an old metal canteen on which was stamped U.S., A.G.M.Co., 1945. It was well dented all over from years of movement on the glacier. I couldnít help but think that someone taking this same hike some fifty years ago was just as impressed as I with the size, beauty and power of this glacier.
