Bigger eyes and a bigger visual cortex. While still being a trichromatic ape. Today studies find Scandinavians have bigger eyes and bigger cortexes than people from Micronesia. Albeit by a much smaller margin when compared to Neanderthals.
If Sasquatch is real? Presumably it would also have larger eyes and visual cortex. A handy adaptation if your ancesotrs hung out in Siberia to Beringia to North America. And now lives in dark forests.
The only thing in this discussion I am not in agreement with is that sasquatch know everything that goes on in their environment. Yes, eventually they do but in the interim hunters in tree stands have sightings. That tells me you can get lucky as they're passing through and they will have no idea you're there.
