Hey Gracu....If someone asks me why you joined geology? my answer is I was undecided about my major until I saw brochure of Department of Geology, hanging on the wall of Tri-Chandra Multiple Campus. What I found on that brochure was luring description of some of their fieldworks outside the Kathmandu valley with other prospectives of study. And then I decided this is going to be my career. 

So Yellowstone National Park is still in my list from US and I am eyeing for a trip to Antartica.

A more complete list of my dream destinations will include 
Chocoloate Hills, Philipines
Saler de Uyuni, Bolivia
Gateway to Hell, Iceland
Stone forest, Madagascar
Fingal's Cave, Scotland
Great Blue Hole, Belize
Great Barrier Reef, Australia
Crystal Caves of Giants, Mexico ( someone told me that they have already filled water in that cave and it is not visitable any more, so sad )
Hell Gate, Turkemanistan
Wave Rock, Australia
I went to Alaska last summer but never got chance to watch Aurora Borealis, so one more time  for that mighty northen lights....

this list goes on but time and money ......never enough!

I still have long list of camera lenses and accessories in my bucket., needs to consult with Juggy /Jacksparrow/Umesh or other pro phtographer in Sajha ..
