Thanks to @rayluis1988 for pointing this out in the Santa Monica, CA thread that for grey pin sites on the Tesla map that have a driving direction link, it points to the actual site where Tesla is planning (or already building) that particular Supercharger. The address for Snoqualmie Pass site which has moved to 2024 target opening is 601 WA 906 which is the Summit Inn and Summit Pancake House. I will look for permits and update here as they are found.
