Answer — Friday Foto Quiz

As Ken Burns puts it, Nation­al Parks are Amer­i­ca’s best idea. This under­ground Nation­al Park is Carls­bad Cav­erns, locat­ed in New Mex­i­co. I believe the for­ma­tion is named “Giant Dome” and resides in the Hall of Giants.

We vis­it­ed the cav­erns in July of 2007. I had just bought a Nikon D80 and was learn­ing to use a DSLR. the low light­ing of a cave was the chal­lenge. We had not yet envi­sioned our light draw­ing project. I was con­fused as to why a white LED flash­light made the for­ma­tions appear blue. I’ve learned alot about LEDs and white bal­ance since then.

This is a great place to vis­it. The scale of these for­ma­tions is lost by not includ­ing peo­ple in my pic­tures as a ref­er­ence. Plan to spend sev­er­al days here to get the full expe­ri­ence. The main self guid­ed tour is mind blow­ing. Then sign up for guid­ed tours to low­er lev­els and oth­er near­by caves. The his­to­ry of those that found and explored the cave is fas­ci­nat­ing. Stay for the night­ly show as 400,000 bats fly over your head as they leave the cave entrance. Then go take the main room tour again because you missed most of what is to be seen.
