I don't think that Kalet is one of them though...
I actually share the following page with Brian (he is the owner; I am the admin):
http://www.summitpost.org/park-range/182864
When it was first added, the information was a little thin and I asked Brian if I could help with it and added a bunch of info. I thought the end result was pretty good working together on it.
My own thoughts concerning the page in question:
If there are errors on the Avalanche Gulch page, that they should be pointed out and Brian should have a chance to fix them.
People should improve a page if they adopt it, and make it as accurate as possible. People also shouldn't be afraid to point out inaccuracies either.
As far as the Avalanche Gulch page goes, here is it in current form:
http://www.summitpost.org/avalanche-gulch/155406
To me, it doesn't look bad at all, but I've only climbed the opposite side of the mountain so don't know what inaccuracies there are (which as you point out, it's better to know before voting, but not always practical for every single page on SP).
If someone points them out and Brian fixes them, I see no big issue.
Personally, I think we should give Brian a chance to update the page(s). It appears (to me) that he is updating one right now. [All of which I said in the elf discussion on the matter].
I do not like inaccurate pages, but think that active members should be given a chance to fix them before being called out (and I mean no offence to anyone who does or did).
Here is one I did call out, but only because things weren't fixed after six years and most of the page was inaccurate (inaccuracies have since been corrected by the elves):

I know there are some issues with some pages Brian adopted, but now that he's aware of them, he should be given a chance to fix them (maybe give him the benefit of the doubt and see what happens). That's all I can say.
