Finally a snow fall last weekend with snow so pure that when I shovelled it off the balcony it left a puff of the finest snow smoke in the air – sorry, no sun so no photo.
Next task was to set the Cross Country Ski Trail for the first time this winter. There was enough snow for two full days excellent skiing. The trail now has room for 3 levels of skier. The delightful trail on the second day showed that it is shared with deer and cayote judging by the tracks. All I need now is more snow and more skiers.
(The map is under development. Google mistakenly thought I was trying to edit their view of Perrysburg and I failed an audit of my changes by one of their “trusted reviewers”!)
Meanwhile “Munger Mogul” looks like this, with a nice herringbone climb up and easy glide down towards “Belazi Bowl”.
The final winter work is the perhaps surprising task of watching for meteorites. Brian Pejovic in “Man and Meteorites” says about 10 tons per day of space stuff land on earth. Roughly speaking that converts to just over one small (1/8″ or 3 mm dia) piece per square mile per day. Winter ice is the perfect place to look for one. I checked that they don’t melt through even though they’re very hot when they land by heating a variety of different size stones, from the dirt road by the river,
to yellow/orange color (about 1000 C or 2000 F).
I put them on ice and watched them partially sink as they melted the ice and cooled.
By the time they had completely cooled they had only sunk about 2/3 of their size, no matter whether they were large or small. (Big ones have more heat but would have to melt more ice before they could sink out of sight). So this shows that hot meteorites probably don’t melt through ice when they land.
Another test I did for the bigger ones was to lob a 5 lb. rock onto about 2″ thick ice, from a height of around 20 ft. While the rock punched a hole in the ice, the water behind it prevented it from going through like a stone through a glass window. The rock simply bounced a short distance away.
From all this I conclude it is well worth watching for odd stones in the very small to tennis ball size range when you are out on the ice.
One of the best ways to increase your chances of finding one is to increase the search. So if all the blog readers look we actually might catch one. Let us know if you do? A bigger one is very valuable – pick it up carefully with a clean paper to keep it pure.
