Does anybody know how I can get the past weather data for Denali (for the heights of 17,000-21,000 feet). There is a good resource for current weather - http://www.mountain-forecast.com/peaks/ ... casts/6194 - but it doesn't have records of past weather. I tried to do Web Archive but was able to retrieve data only for June 7th, 2011 - http://web.archive.org/web/201106072042 ... casts/6194. I specifically need the data for May 31, 2011... I found the historical data for the years 2000-2007 when the temperature ranged between -15F and -25F which is not the precision I need.
This would help me plan my future expedition by benchmarking the effectiveness of heat-insulation of the equipment that I used on Denali during that period...
