Your self portrait gives a very surprising scale to the vortex, especially for one, me, who hasn't made it there yet!
Really fine stuff, Bart. All are delightful, but the delicate colors in the 2nd and 3rd are just wonderful!
Cool stuff here. Looks like you had a blast. My favorite is #3. What a kind of mind blowing angles on that shot. Very cool! The last one from the boneyard is really cool. I am so glad I found that the last trip, I can't wait to explore it some more next time.
