We try to keep the Pacific Crest Trail Data Book (a compilation of distances between landmarks, facilities and other features on the trail) as up-to-date as possible and we'd love your help!

If, during your travels, you discover something that should be changed in our Data Book, please let us know by sending an e-mail to Ben Go (click on Ben's name to send an e-mail right now).

Please include in your message as much as of the following information as possible.

• State/region (Southern California, Central California, Northern California, Oregon, or Washington)
  
• Guide book section/map
  
• Landmark(s)
  
• Other pertinent/identifying data

Thank you!
