Having sampled the delights of KGYR from APR-AUG I would say that there were very few days when there was a noticeable x-wind factor compared to GA flying I have done in the UK.
I also doubt that anyone could land a PA28 or PA34 in a x-wind of 35kts. It might have been gusting but not 35kts, if it were varying that much I would expect you to be off the side of the rwy in seconds.
