"Almost a painting!"
We do not know where the above remark comes from because Dr. Mark did not cite the source. It is not unlikely that Woodward would have made and oil of this subject, he had painted the "hopper" of Mount Equinox around the same time. Perhaps that is why he never painted the Greylock version, because he already had Mt. Equinox done. SEE BELOW FOR MORE...
The term "hopper" in reference to Greylock is, "a glacial cirque or bowl-shaped depression on the western-side of Mount Greylock," according to the You Asked Why column of the Berkshire Eagle
There is another chalk drawing of the "hopper" made in 1931 and exhibited at the Myles Standish Gallery in Boston named, The Hopper at Greylock.
'The Hopper at Greylock' is a fine 'close-up' of the hills, shows the depth of the distant color and the sky when the sun comes through rain clouds.
The term hopper assigned to this western section of Greylock comes from the traditional shape of grain "hopper" or feeder if you will.
