I'm in the Kangchenjunga (28,169 ft.) region of Nepal documenting Himalayan climate change and glacier melt rates. Now await Tibet permit.

Soft landing on paved airstrip at Lukla. So different from the bone-jarring landing on rutted dirt airstrip in '79. Miss the dirt.

Wonderful trek up the Namche Hill. Clear view of Everest from same spot I first saw it 33 yrs. ago. Many butterflies and ladybugs on the way

Namche is bustling and busy with climbers and trekkers headed for Everest. Yak trains and heavily laden porters on the way too. #icegallery

Great to be on the way to #Everest Base Camp with the photo exhibit. #icegallery

Up the hill to Khumjung today. Fond memories of working here on the film "Sherpa" in 1980. Dinner w/Sherpa friends tonight. #icegallery

Great dinner in home of Pema Chamji, Sherpa friend of 33 yrs. She served potato pancakes & chang. Nothing like home cookin'. #Himalaya
