Full field day yesterday in Glacial- we went out looking at varves and deposits in a proglacial lake system, which was pretty interesting, and helped take my mind off of things. Site number one was in Warren, where we got to cross a pretty cold stream and then up a wet, clay rich enbankment, which was lots of fun. The entire thing was composed of varves, which was really cool to see for the first time, after learning about them over the past two years. Varves are a glacial deposit that are linked to melt seasons in a pro-glacial lake. Basically, Glaciers dump a huge amount of sediment into a basin, and after the larger things settle out, such as sand, silt is carried further and deposited. During the time that the lake then melts over, currents essentialy stop and clay is deposited. Then the melt season comes and the cycle is started over again. The result is a silt-clay layering that represents an annual cycle, as accurate as tree rings. And when it’s wet, it’s really slippery. We had one person fall and bash his head, and I slipped a couple times. Got my boots soaked when we crossed back over the stream.
The second site was different, a huge sand deposit that showed ripples and other lake bottom structures, with a few varves thrown in. Fell there too. We also got kicked off the property, because some idiots decided to build houses on top of the enbankment, which is about 60 ft high, and eroding back fast.
Then comes the annual haunted hayride. First night was last night, went off pretty well. We had just a couple people from the club come, but we had a couple of rooks help us out. We ended up running a flying monkey, which was interesting, but we were also given a chainsaw, and someone brought their airsoft M4 and a paintball gun. Basically, they were soldiers on patrol, and I was a chainsaw murderer, who gets shot, comes back to life and killes them, then takes off after the wagon. Worked pretty well.
But know my knees and back is pretty sore, and my voice is starting to go. Two more days…
