We had a long journey to get there, look at the trip: 8 airplanes (Marseille-Brussel-Reykjavik-Montréal / Detroit-Denver / Denver-Lisbone-Brussel-Marseille), 1 bus (Toronto-Detroit) 2 rented cars, plus of course, a lot of walks.
That was also a nice adventure for my wife and two of our grand children, when making a sort of quick-off about our holidays, our two kids says that the eclipse was the number one without any doubt, long before the bears family just in front of our car in the Teton park, or the geyser and colored lakes in the YellowStone one. The second event for them was the perseïd shower from the Megantic observatory in Quebec, but that’s another story.
For the eclipse the place chosen was marvellous, a special camping was set-up close to Riverton in the Wyoming. The place is in an Indian reserve along the nice Windriver. What a warm welcome we had here ! For the american fellows here I have to add that you have a very very nice country guys and we had a lot of fun with so nice people... my sketchbook is full of common (non astronomical) souvenirs.
I initially planned to be exactly on the line. The day before we spend some time to find the best place to be, but that was on the middle of nowhere, under the sun for a long period with no real nice landscape to take advantage of. Also the traffic could maybe be an issue. We loose maybe 9 seconds of totality but decided to stay in the camp site.
So that was directly from our tent place that we stay and enjoyed the eclipse.
As for others here the transparent cloud was not an issue, nor during the partial phase of the eclipse, nor during the totality because at this moment no clouds were present around the sun. This phenomenon of “clouds off” was already described by others here.
The watercolor was done during and just after the eclipse, the support is a A4 Moleskine sketchbook with 200g paper not really perfect but lighter for the airplane... I just hilight the sun's disks and the corona after scaning.
For comparison with the other eclipse we saw - 1999 in France, this one was visible with a less dark sky, so less stars were visibles, but a more brilliant corona and much better weather.
Looking at the horizon it was like the sun was rising all around the 360°.
During the totality I was catching 3 rapid photos (sorry sketchers) to show the corona with 3 directions (120°) of a polarizing filter, the polarizing light of the coma is something very special. When I was young I did a long work at the ORB (Observatoire Royal de Belgique) to analyse three pictures made during an eclipse made in Kenya, that was more or less in the year 1970. I plan to make a corona sketch with those 3 directions in a while.
What I like to do with children is to use the pinhole effect, very safe, this is the diffraction of the sun light through some holes in tree leaves.
Here, before totality I made a sketch using directly the shadows position, (lot of small croissant shapes) on the paper. The afternoon we went to the Kingston post-office asking to add the special event stamp on the page.
And here a picture of the team just after the totality showing the same effect.
Voilà, I hope you can compare your impression with mine.
