Space Station view

Astronaut Scott Kelly flew over Kilimanjaro a couple mornings ago (17 August) and tweeted the image above. This is a low-resolution version of what NASA will hopefully post eventually, yet adequate to see some interesting features:
  • White areas on the mountain are primarily glacier ice. Very small areas of seasonal snow are visible within the summit caldera, on the western flank (e.g., Breach area), and to a greater extent on the south side - formerly occupied by the Southern Ice Field. 
  • The mountain's largest ice body (Northern Ice Field) is the northernmost glacier, and both the split and more-recently developing holes (n=6) are visible; the glacier's total area is less than 1 km^2. See the post below for detail on this glacier, about a month prior.
  • The east-west oriented ice body to the southwest of the Reusch Crater is the largest remnant of the Furtw√§ngler Glacier. Groups sometimes camp just south of this glacier.
  • The Decken Glacier is the skinny (40-50 m wide), southernmost ice body visible above. Narrowing of this glacier has been quite rapid; the Heim Glacier (slightly to the west) underwent the same ablation pattern 5-10 years ago and is now just a tiny remnant at ~5,300 m.
  • Kibo's adjacent peak Mawenzi is visible at the lower right corner of the image above, with the "Saddle" area in between.
  • Amazingly, considering that the ISS is currently at an altitude of ~400 km above Earth, the trail above and below Birafu Camp is visible, as well as the trail between Karanga Valley and Birafu camps!
