• Summitpost : A great site with excellent climbing information. The content is from real climbers and run by Josh, a real climber living in California. It has become very popular by creating a community for climbers. The best community site on the Web. It is free with limited advertising.
• MountEverest.net: An excellent site with outstanding coverage of high altitude climbs throughout the word and year. It was created to follow a real expedition in 1999. They continue to expand their coverage with new technologies and now receive live feeds directly from expeditions transmitted to their site via their own Contact Software. The site has evolved over the years to have a more journalistic feel complete with editorials and challenges to to questionable claims in the climbing world. Somehow they seem to be getting the best stories before anyone else. It is free and there is almost no advertising and the layout is easy and pleasant to read.
