Wilderness hikers take note: You cannot assume that a wilderness trail will be passable and followable! Trails may be blocked by brush or downfall and/or without apparent tread, especially for secondary trails and "use" trails. Brush grows quickly in these wilderness areas, extensive falls of fire-damaged trees occur after strong winds, trails along the steep slopes are very subject to erosion, and maintenance is spotty. Know before you go - you may be very glad you did! I've encountered too many hikers who had no clue regarding the difficulties they were going to encounter, and who did not end up with the wilderness experience they had anticipated.  Where tread is sporadic and/or confusion with animal trails possible, use of a GPS loaded with accurate trail data is recommended! Left-clicking on a Trailmap line or icon displays an "information bubble" which for trails includes the latest summary of hiker-reported trail conditions and a link to the full VWA Trail Report (when available), as well as trail distance, cumulative elevation gain, and GPS data.
NEW: Wilderness trail width => Usability Wilderness trail line widths are now altered to match their usability based upon VWA Trail Reports over the last 365 days (except older reports are used to reach a 3 report minimum), the widths ranging from 4 down to 1 for, respectively, "wilderness freeway-to-clear, "clear-to-passable", "passable-to-difficult", and "difficult-to-impassable" conditions. Do recognize that these ratings are rough and are applied to the entire trail, whereas in actuality conditions may differ greatly along different sections of a trail - as always, consult the VWA reports for detailed trail information (available as a link on a trail's info window popup). When no reports are available, as for state park and use trails, the nominal widths are: trails = 3, usetrails = 2, "historic" trails = 1. This is a "planning" feature so implemented only in the browser and GoogleEarth versions, not in single-page-printable and Garmin-format trailmaps. Line widths are updated daily.
