Does the summit of a small mountain offer better seeing? I have a small amateur telescope, and would like to defeat the atmospheric seeing conditions as much as is possible.

Fortuitously, I happen to live fairly close to this lovely patch of bare elevated rock:

It's a granite peak about 3,155ft (960m) above sea level.

Would this peak be expected to have improved seeing, as compared to the seeing from an adjacent valley on the same night?
In terms of steadiness of the air and hence stability of the image (ie ability to see fine detail on planets or split close double stars), it could go either way, depending on the atmospheric conditions, including wind speed and direction, and the local topography.

In contrast, valleys can sometimes provide better seeing because they provide some protection from atmospheric conditions.

However, and all other things being equal, you will probably have a higher limiting magnitude (ie be able to see fainter objects) from the top of the mountain.
