How long they survive all depends on the weather. Beck designs and redesigns the patterns as new snow falls, sometimes unable to finish a piece due to significant overnight accumulations. Interestingly enough, he said, The main reason for making them was because I can no longer run properly due to problems with my feet, so plodding about on level snow is the least painful way of getting exercise. In a comment in his Facebook page he says: “As for ones state, very tired, usually I continue until i am too tired to do any more”.
For another artwork he says: “It is tricky to know where to put the center of these things. It’s annoying when part of the design goes up the hill to the left, but if you use the lake in its entirety part of the artwork gets hidden from what is in other respects the best viewpoint.”
He has also marked one of his works with letters and explains what minor errors he has made. I have put the comments as caption.
All things being equal the sun should be as low as possible for good photos, the obvious problem here is the lake starts to go into shadow.

I hardly put a foot a foot wrong with this artwork. At X I seem to have got off line, and at Y I took a couple of steps in the wrong direction before realising my error. Other than that there are just minor although noticeable innaccuracies.
