There is information online at the Yosemite NPS site tracking the historic opening/closing dates of the Tioga Pass Road, along which you did your photography.
I'm very familiar with that region, having gone there for a number of decades - camping, hiking, backpacking, cross country skiing.
IIRC, the closing dates for Tioga Pass road have been as early as October (we were stormed out of a late season pack trip in the area a few years back) and as late as January! More typical closing dates seem to be in the October/November time frame - once the first "real snow" falls they don't plow the road and it closes.
Opening dates also vary quite a bit depending on a range of factors including the snow depth and how early/late the thaw happens. I haven't checked the actual record this morning, but I believe that April openings have happened, though they are quite rare. May or June openings are more typical. I distinctly recall one season in the 1990s when the road remained closed until July.
Once it opens, conditions are often still quite winter-like. At first no facilities are available, in wet years the creeks can be dangerously high, and there can be quite a bit of snow still on the ground.
The normal "high season" along Tioga Road is probably more or less mid/late July through the first week or so of September. Those of us who go there a lot and try to escape crowds aim for mid September though the eastern Sierra aspen season in early/late October, when the area is stunningly beautiful but far less populated. But once you get to this part of the year you can no longer take the weather for granted. While it can be sunny and beautiful, Pacific storms often begin go come through and can close the area for a few days... or the whole season.
It's funny when someone posts to look like a smartass but just ends up looking like a dumbass.
I am lightened up.
My point is not to make assumptions and exagurations. You can think anything you like - I'm still right, it's not a summer only road by any means, which is all I ever said about it.
