Yes, colder weather bring many problem…ski lift stop, ice fog..but several things we could enjoy out side!
cold days…time for color bubbles

Denali Project
We need finalize Denali proposal very soon for next summer (June). Idea is that to install (just) temperature sensors on air, ground surface and ground with Iridium based satellite datalogger simmilar like Kilimanjaro setting.
First candidate site, at the West Buttress between 14K and 17K Camps. You will see the trail lower part of this picture. But not much rocks exposed…
IR image of the same location, Rocks were already positive temperature on May 10 by the solar radiation.
Around 14K Camp (medical Camp) is another candidate (picture below). But steep and narrow open sky for satellite communication…
But anyway, we need permission first!! That try to negotiate next week.
near football field, climbers walking on snow
surface temperature at the same time (May 10, 2005) around Denali Pass (Annual Mean Surface Temperature -27dC)
pipeline crossing the Tanana River
Cold day below 20s, Tanana River still open and generate many fog near Delta Junction
Seems Golden Gate Bridge!!
Moon rise near Summit Lake
Tent for snowmachine trip
tent selection: Tent is definitely important items for this trip. Especially inter-village distance is much longer in Arctic Canada than Alaskan’s!! We think to use Alpine style than the classic Alaskan winter travel tent. This is ideal 3 layer dome tent used in Antarctica and Greenland…
3D visualization for 100 years glacier & permafrost history on Kilimanjaro
We try to develop 3D visualization material for 100 years glacier & permafrost history on Kilimanjaro working with Vavilov Institute for the History of Science and Technology of the Russian Academy of Sciences
Happy Thanksgiving!
Typical cold day and nice sun set toward to the Denali
Expedition design
Cleaning sextant and thinking about alternate plan for the snowmachine trip. I got many problems now…No body interesting about 20 years old GPS but people still looking for sextant. It’s beautiful and true today. It will be sure beautiful and true in a future too! That should be the design of the expedition too!
Temperature data, freezing degree days at Joy School (Creamer’s Field)
Addition of the ground surface freezing degree days!! It was typical cold winter reached 2600 degee days in 2011-2012. Our longest frost tube (5.3m deep!!) works and frost depth reached close to 3m in March 2012!!
*freezing degree days plotted reverse scale
Ground surface temperature at forest floor (Annual mean -2.5 degree C, Max. 17 degree C, Min. -32 degree C)
