I used to be able to tell you when the seasons would change, such as from November to the end of February. If not the beginning of March was winter, and you could expect snow and cold weather, March to the end of June or the first of July was spring or summer weather, Summertime was the end of July to the end of August, and fall was from September to November.  This year we didn't get snow that stuck until almost Christmas, and it lasted until about 2 weeks ago when they closed Snowbird Ski Resort.

I think that the waves are the folds in the plate where new earth is being created at a faster rate over time. I also like how in this picture you are able to more clearly see the folds in the sea floor .
