Wonderland Trail List
Check out lists from people's journals at Trailjournals. No everyone put a full gear list up.
Most of my lists are maintained in Excel but written out as HTML. So you can view the results with a web browser, but if you open the file in Excel you can set parameters at the top of the document which effect the contents on the list.
Cost Contained Ultralight List: This is a two season list I helped a friend make several years ago. The layout is based on the BPL.com fast and light list. The list has has been somewhat generalized so it might be useful to others.
High Perfornmance, Good Value, 3-Season Gear List: A friend who had to start from scratch asked for a gear list which would have similar performance characteristics to what I am using with an eye to keeping the price reasonable.
Mark's Three Season Gear List: This is the list I used on most trips. It is designed to maximize my comfort while simplifying the choices I need to make. Most of the items listed live in my backpack or a large cotton storage bag... ready to go. This list covers conditions that are warmer than 20F without major snow.
Mark's Super Ultra Light Gear List: No longer current. This is list I use on light and fast trips (less than 3 days) where my goal is to go as light as possible. Typically used in the summer, though I have done trips near the coast during the "winter" using this list.
Mark's Full Gear List: My master list which has everything I own and might take into the back country. Set parameters and it will tell me what I should take based on past trips.
Mark's Heavy Weight -vs- Light Weight list: How I went from a 41+lb base weight to 11lbs (or in many cases less)
