It has been mentioned, but it keeps getting ignored--how bad paving is for the environment in these mountain areas. Do you know what runoff from parking lots where cars have dripped oil/other fluids does to a stream? It kills fish, for one. Given that so many western resorts are on Forest Service land, this is a non-starter.
I was trying to remember if I have ever seen a paved lot, outside of say, the Vail garage (doesn't that fund their free transit system?). I can think of a couple tiny, very expensive patches of asphalt, I think, at a couple places, like Sun Valley. I don't think there is such an animal here in WA. But since they are usually covered in snow/ice I guess there could be something I missed.
I don't think environmental impact is intentionally being ignored. But just that different things are being discussed. But yea I can see your point about that.
That said if we want to get moire into that and I wouldn't disagree but there are other things to consider with an unpaved lot just the same imo......
......as for oil and fluid drippings? That stuff going directly into the ground via an unpaved lot is not really any different and can have the same affect as well as contaminate the ground under the gravel lot. The rains and also water from melting snows then carries that through the ground and can spread just about anywhere the water takes it which could be a stream too not too mention feeding the roots of surrounding vegetation, trees, etc. . And also I think alot of the almost often black in appearance color of the mud itself is contaminated fluid mixed which gets on your boots, tracked indoors, in your car, etc....there is no getting away from that imo either way and is an ugly evil of the situation regardless which way its done.
Then we have the dry days when the huge dust cloud in and surrounding the lot gets all over everything as vehicles kick it all up all day long. Id be certain much the dry flying dust cloud is the same contaminated dirt particles. Not just us humans breathing it in, but also any animals nearby as well, And it also settling on all plant life leaves and such in and surrounding the whole area. Not only animals then eating the vegetation, berries, etc, whatever have you but then washing off the plants (via precipitation) and into the ground contaminating that and possibly the same stream once again.
I not trying to be sarcastic here but only in the sense if one wants to consider the environmental impact we have to look at it from "all angles". The amount of dirty cloud flying around is not a little but is huge. The air is filled with it. Just look at a clean car you pulled in with and what it looks like after you leave. I mean that is in the air and it is a whole lot and is going to do all the things I mentioned. And imo a lot of that dry dirt thrown up in the air would be the same contaminated soils from the fluid drippings in the lot.
So I honestly don't know if the affect of paved runoff is any more evil to the environment than the affect of all the things associated with unpaved mentioned in above paragraphs.. The ground, the air, and just about everything surrounding it all. Seems like lose/lose either way as there is no way around it regardless.
