Superior mirages- I have seen quite a few of these over Lake Huron since we have been here. Usually of ships traveling the shipping channels, once of some sort of structure or part of a city, we were not able to see it clearly but knew it was a mirage, it was rectangular and seemed to float in the air above the water. Can we trust what we see? even if our vision is excellent, our perception and our interpretation of what we see can be skewed. Examples: Optical illusions, a la Escher. Sleight of hand magic tricks depend on fooling our perception deliberately. others? www.islandnet.com/~see/weather/elements/supmrge.htm

disappointing, but I know that area is very heavily hunted. looking forward to hearing about the trip.

I joined the local pool this winter after realizing that I will not be going out in below zero temps to walk. Walking is the most natural exercise for human beings, we are designed to be walking machines. I too find use of exercise equipment incredibly boring, but will walk long distances outside happily since there is always something to see outside. I have put myself on a diet of nothing but veggies and lean meat (nothing fried). Lost 10 lbs so far, trying to lose another 20 to 30. Learning I can't cheat at all. "if it tastes good you can't have it is right!" I hate it! I am trying to find other areas in my life where I can still find enjoyment instead. Swimming was great for me, toned and helped gain muscle mass. I was in not good shape, and started by doing "water walking", using resistance of the water and just exercising untiltil I was tired. Added about 5 minutes per week until I was up to a half hour a visit. minimum of 3 times a week, 20 minutes of exercise that makes you breathe harder is the goal to aim for (cardio/respiratory fitness).More is better if you can handle it. Then I was able to do laps, slowly,and for only 25 minutes, but that helped increase my cardio/lung capacity. As soon as it was nice outside I switched to walking and try to walk as much as I can. Come winter, it will be back to the pool. Of course not everybody has access to a pool. There are all sorts of exercises I can't do , due to physical limitations, but I think the key is finding ones you can tolerate and being consistent in doing them. I hate the idea of doing an 'exercise routine'.I hate dieting, quitting smoking was easier, because you could just stop doing it, but of course you can't just quit eating. keeping on keeping on, some days better than others. even 3 steps forward and 2 back is still progress.

snuffy, do you do anything in your garden to prepare for excessively wet weather? Just wait it out? interesting weather patterns all over the past couple of years.

politics, again? If I had you guys squabbling in my kitchen I'd take a broom to you all and tell you to take it outdoors!

Sample 9 was epidosite- quoting: sample #9- Epidosite- epidote grains intermixed with hydrothermally welded quartz grains . Ann says it was the densest/heaviest of the samples they looked at. If I remember correctly it looked similar to Wampidy's picture in this thread. But do I remember correctly? forum.rocktumblinghobby.com/thread/68838/unakite-epidote-lake-superiorI still have lots of notes and photos/videos to sort through and there is a load of information yet to be added for a complete report on each specimen. I will be working through it and adding more information as I make sense of it and am able to in time. That's it for now. Thanks for looking. Thanks again to Ann and Wayne for giving of their time and effort so generously to gather all the information and make it available to me. I am learning more each time I go through the notes and pictures/videos. So grateful for this opportunity, what a blessing! comments and corrections welcome!

Also noted that pyrite seems to infiltrate or be included in almost everything here! One of the biggest informers for me was that the nuggets and particles that I thought must be nickel/iron in the impactites and in other rocks turned out to be pyrite. I knew pyrite was common in this area. No nickel/iron was found in any of the samples. Sample 8 was the biggest surprise by far. quoting report Sample 8- Dense chlorite or Chlorastrolite - This sample appears to be a low pressure hydrothermally altered gabbro. This metamorphosed gabbro shows all its pyroxene crystals have been altered to very fibrous grains of actinolite. Actinolite grains are very dense but only show minimal compaction. this microscopic photo clearly shows the actinolite "tail" developed from the pyroxene crystals. now commenting, not quoting. Wayne thought this was on its way to becoming chlorastrolite- but not quite arrived at those changes, but borderline.

sample 6. beginning to notice a theme, it seems most of the things I pick up are metamorphic. quoting : sample 6- Metasedimentary Greenstone- Silt to clay size quartz grained rock. Fragmented pieces are filled and surrounded by chlorite. Minor amounts of augite are seen. There is secondary pyrite noted in small amounts. Larger sections of quartz show welded margins, secondary overgrowth and fracture filling, indicating possible low temperature hydrothermal alterations.

I love this stuff. I find it all over and have a hard time resisting it. it seems to come in gray and green base colors but that could be surface staining. quoting again. Sample 4 _ Conglomerate- sub rounded to angular fragments are seen suspended in a finer matrix. Fragments consist of quartzite, granite and basalt. Plagioclase and orthoclase are both noted in large pieces along with quartz and the rare biotite grain here and there. Some of the quartzite fragments contain sericite mica. Several garnets were noted along with secondary pyrite filling the cracks and voids.

This was an interesting one, we come across quite a bit of it, with the bits embedded in it, I always thought of it as some sort of conglomerate. quoting the report again: #3 Highly metamorphosed siltstone "semi schist"- the sample is highly fragmented with relic bedding seen within the broken fragments. Highly quartzose fragments are surrounded by abundant chlorite mica. Lots of secondary pyrite speckles the entire sample. Iron Oxide staining within the fractures is evident. Occasional fragments of very coarse and very fine quartzite material are seen.

Prosopagnosia, the inability to recognize facial features. www.faceblind.org/facetests/I took the tests and was distressed and quite uneasy throughout the entire process. I think it is because the faces presented are not real but computer generated. I find computer illustration and computer animation upsets me. Does anybody else get uneasy when watching computer generated images? My discomfort is primarily when viewing subjects that portray living beings, whether human or animal.

I remember working in a store which began to carry the first Texas Instruments digital calculators back in the early 1970's. A man came in to buy one and held it up to me saying "take a good look, the science and the technology of these things will change the world." of course he was right. watching with interest.

wow, well worth the effort and the aspirin you probably had to take afterwards. Those are beautiful! You must have hit the mother lode!

second, fifth and seventh samples were all impactites, my surmise is that they are all from Sudbury impact event, since the impact site is 150 miles away directly across Lake Huron and I have found many Black Onaping pieces locally. Some of the quartz in the impactites had bubbles or had flow lines and also showed that it picked up debris while still soft/liquid.(inclusions). It is my understanding that Wayne was delighted to find shocked quartz as well, and to have a sample of it in hand. showing quartz with inclusions Shocked quartz showing fracture lines where the shock waves of impact have shattered the crystal. I have to stop posting for the moment, more good stuff to follow. I am so grateful to Ann and to Wayne for all the time invested and the trouble they have gone to in making this information available to me. There are just incalculable hours of preparation, photo taking, video making, report preparation, consultation, analysis and so much more invested here. I will be looking at photos and videos and reading and trying to understand everything in all of it for a long time. Great material for study. You both have given me an unparalleled learning opportunity and I deeply appreciate all your time and trouble. There is no way to express my gratitude, and the tremendous excitement of having all of this information at hand. Thank you so very much!
