if you can you should try to stop by a sciency place local to you where . Usually libraries, schools or related. it will be easier than trying to track down glasses.
this is like the main event for the amateur astronomers to share their hobby, and typically they'll set up their eclipse prepared telescope and have projection boxes that everyone can take turns and can share glasses. especially if you arent in totality most people will look for maybe 30sec and have their fill and ready to share.
that being said, if you're set on keeping to yourself, i suggest stopping by a welding supply store (not just homedepot) and asking about the welding lenses before you just say f it and only use your solx ski goggles. there should be easy supply there.
however despite what NASA says, and this is at your own risk; the practicality is rarely any welding supply carries shade14 lens. so most likely you can pick up shade 13 and limit your exposure and take breaks. the math says that over 12 is barely acceptable. Or try stacking (but should be way over compensating like a 10 and a 9), not just 10+4 =14.
but you can test beforehand and the sun should be extremely comfortable to look at and very dim.
your skiing on the slopes with the wrong goggle choice for a day probably causes more damage than watching the eclipse with a shade 12 lens instead of a 14.
again this is against nasa advice so again at your own risk, but its a better alternative than wasting hours trying to find eclipse shades and getting frustrated and looking with your ski goggles.
