So I'm assuming the original question really was " North Palisade glacier? Or no?". Since I see no U-Notch, it can't be North Palisade. However, Clyde Peak (which I agree is the mountain depicted) is a part of the 'Palisades Group', as defined by all the climbing guides, So, technically, the painting does depict a Palisade Glacier. Nice painting, BTW.
