Wow those are great. I've never been to Arches, in fact being from the East I've only had a couple of trips out West where I had a chance to spend some time shooting that type of landscape.
Nice vivid colors and great detail. Hope to get there sometime
What lens were you using?

These two I took with 24-70mm 2,8L and polfilter

Excellent perspective,Julian. I like it alot.

Just got back from Moab myself. It was more a climbing trip than photography, but I got some good stuff anyway. Are those photos from Devil's Garden, or maybe the Furnace?

I love how dependent photos in Arches are on the weather. The right sky can make a good photo amazing. Last week was mostly bluebird skies for us; nice for climbing, though.

Getting low in the first shot c/w the sky is fantastic!

What time of day where these taking?

Well Done!!

I took these images at about 11 am

The first is near by the parking place at the end of the road.
The second place you reach after 5 minutes, when you walk from this parking place to Delicate Arch (or any other Arch you can reach from this place)

Nice work there. I love shooting in Moab and its surrounding areas.
