Forty Day Backpacking Plan: Lake Tahoe to Mount Whitney 2002 sticky icon

Below we have one element of my trip planning notes from a forty day hike I took from Lake Tahoe to Mount Whitney during 2002.

I've done Tahoe to Whitney Trips in 1999, 2001, 2002, 2009, and 2012. Injury is the determining factor in my "backpacking year" scheduling. If I am fit I am backpacking.

Bear News and Research sticky icon

 

The repository of Bear news, research, and stories we come across.

I've written about my experiences with High Sierra Black Bear Behavior in the Trail and Camp Skills section of the Trail Guide. Remember, bears act differently in different locations, and can be quite unpredictable in most situations.

The World of Insects and the Spiders that Eat Them

We've got worlds of wonder in the High Sierra looking in any direction. The ground and sky are full of vibrant insect communities. Some, like the mosquitoes, are winged devils. Others are winged delights. On the ground we find spiders trying to catch and eat them all.

This forum started out as the Spider Forum, but has been expanded to include the various insects we encounter that are not Bees, Butterflies, and Mosquitoes, which have their own dedicated pages.

Safety First! First Aid Kit for High Sierra Backpackers sticky icon

 Spring has come to the eastern Sierras and time to spring clean the first aid kit. Alex has provided excellent information about his first aid kit in the gear list. I am an avid day hiker, so the contents of my bag are a bit different. I also have extensive medical training and access to prescription drugs, so I try to keep stuff to help out others on the trail. This is the time of year I pull the first aid kit from the depths of my day pack and inspect and refill the contents.
