Cool stuff. I climbed the RNWF almost 21 years ago and I remember looking west as far as I could see from Big Sandy Ledge. It felt like I could see the ocean, which might have been Turlock.

the distance of the horizon that you can see from a particular altitude is given by a simple formula (in which things just work out... if you don't believe me, do the calculation yourself):
horizon distance in miles = square root of your altitude in feet
so at the top of Half Dome, at roughly 9000' the horizon is 94.5 miles, not correcting for atmospheric refraction, which will take you out a little bit further than my site 8 which was nearly 89 miles distant. The horizon you would see from Half Dome would be the hills that define the eastern boundary of the Central Valley.

Since it has been so cold over there thought I would bump this and see what the viewing conditions are like.

Very nice stuff to see again... Ed, your curiosity and drive to action are inspiring.

should be pretty good, though there is still ground moisture (warm soil, but probably getting cooler).
I posted this on another thread, from last week...
lots of "stuff" in the atmosphere at sunset... but this weekend is a full moon opportunity, I'll do a calculation and see what might be happening...
but certainly just shooting Half Dome should be a real possibility on these clear days...

You ever get a rematch with this shot Ed?

Great effort Ed. Thanks so much for the overlay of the names of the peaks etc. VERY cool.

Ed, will you be trying again this winter? I was researching this topic before going up to Modesto a few weeks ago to see Valley Uprising. I knew it would be the wrong conditions anyway, and it was probably the haziest day ever! I'm thinking about trying again in December although I'm trying to think of other things to do in the area because it's a long shot up from SoCal for a slim chance of sighting Half Dome!

working on many projects, including this one...
one of my practical realizations was that you want to be further away from Half Dome because of the Earth's curvature and the intervening foot hills.
The more dramatic shots will be taken from the western side of the Central Valley, like my first image of the Feb 2013 campaign
this is 89 miles away, and on the plane of the central valley floor, so you're looking through a lot of atmosphere.
It would be good to have a clear atmosphere index... unfortunately the "visibility" index that airports report isn't useful... turns out to have a distance limit that is much shorter than the 100 miles, or so, of atmosphere we look through.
It's also possible that adding red filters, as was done in the Lick pano, might help cut down the light scatter, notice that the haze is "blue"
Getting up in the hills is a definite possibility. I have no doubt that we'll eventually get a fantastic image of Half Dome from the Valley... the conditions have to be just right... unfortunately, you'd like to get this in the early morning on a cold clear day (windless) so the atmosphere is very settled. But the illumination of Half Dome would be less than ideal.
Another possibility is to get a look after the passage of a storm with clearing at sunset.
If you want the Moon too, it's making it even harder...

As Ed notes immediately after a winter storm would be best. I can't think
of any index other than smog particulate reports that would help. And, as
noted, airport RVR's are only concerned with horizontal visibility below
decision height (200') and they only care that you can see an object like,
say, a 737 rather than Honnold standing naked on Thank God Ledge.
DMT's idea of getting a little above the really yukky stuff is gud.

getting above is part of the campaign, but the OP is about being on the central valley floor, so I think a shot would be in order...
not that it hasn't happened even in this thread.

It is winter again,,
How is the viewing of Half Dome from the Central Valley?
This seems to be a great year for clarity.
Lots of storms passing thru. Must be some clear days in between.
Any new photos of the Dome, from the valley this year?

Many good viewing days here in the shadow of the Dome. Wish I had a decent telephoto lens.
