I agree with the notion that Michigan is the banana belt of the Lake States--especially since they live in one of the suburbs of Detroit!
During my years in northern Utah, we rarely saw temperatures drop below zero in the Cache Valley, but there were frost pockets in the mountains not far out of Logan that the cold air would drain into and the temperatures were recorded to drop into the -50 or -60 below levels (not including windchill).? Here's a link to a newspaper article on the sinks up in the Logan Canyon area of the Wasatch Mountains... http://findarticles.com/p/articles/mi_qn4188/is_20060218/ai_n16150163/pg_1?tag=artBody;col1 Don ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Don C.

The coldest reading this morning was -44F at Embarrass, not as cold as yesterday's -47F at Embarrass and -48F at Babbitt. Did you hear about the 64 year old woman in Duluth who fell in her driveway and couldn't get up for several hours? Her body temperature was down to 60 degrees, and yet she was revived and now totally back to normal. A few years ago I mentioned that a typical Minnesota grandmother was tougher than a Marine, and this event proves that to be true. Anyway, I have done some research on insect pests, and Gypsy moths, which are just invading Minnesota, may actually have their overwintering eggs killed by the cold in the far northern part of the state. 48-72 hours at -20F or 24 hours at -25F are thought to kill the eggs, and few places stayed below -20F for highs. In the Twin Cities, the cold we have had (daily highs of -5F and lows of -20F to -25F) won't come close to killing Gypsy moths. European elm bark beetles will be probably be knocked back, but not exterminated in the Twin Cities. Hemlock Woolly adelgids and Balsam woolly adelgids would have been exterminated, if they had been here. Emerald ash borer is also not here yet, but it would likely have survived the cold if they had been here, since the species comes from northeastern China and eastern Russia, where it is as cold or colder than MN. I have not been able to find good data on cold tolerance of Asian Long-horned beetle. Lee [email protected] wrote: > ENTS-- > > 48 below--that's nothing!!
