What do the letters like CS, WR, TR, etc. on the maps mean?

Waypoint abbreviations are explained in this blog post.

I want to make a donation to Halfmile’s PCT maps but I can’t find the donate button.

We have decided to stop accepting monetary donations from hikers, but it would make us really happy if you made a donation to the Pacific Crest Trail Association. We know most of you are already PCTA members, so just send them a little something extra and tell them Halfmile sent you. You can use this handy donate page.

I’m having problems opening Halfmile’s printable PDF map files. When try to open the .ZIP file in Adobe Reader it comes up with an error saying it is invalid.

.ZIP files need to be uncompressed (expanded) before they can be opened with Adobe Reader. Windows users can find more information here. Macintosh users can find more information here.

Where I can have Halfmile’s Pacific Crest Trail maps printed?

Yogi, publisher of the popular Yogi’s Pacific Crest Trail Handbook, is now offering map printing services. From Yogi’s web site:

Yogi’s Books is offering full-color printing of Halfmile’s maps at a significant savings.

Matt (Yogi’s co-conspirator) has 15 years experience in the print industry. Over the years, he has maintained his print industry contacts. His strong relationship with Canon USA allowed us to acquire a full-color production printing solution to meet the map printing needs of the hiking community. The result is that we’re able to offer this printing service at a lower cost than other printers.

Print output is extremely clear. Maps are printed on both sides:

  • 8.5″ x 11″, premium 70lb text weight paper
  • 98% brightness for great contrast
  • 94% opacity eliminates show-thru of reverse side image

Why use Yogi’s Books’ printing?

  • No need to join a group bulk order to save money
  • Fast turnaround – map sets will ship within 2 business days of order
  • Significant cost savings

If you decide to use a printer, it’s between you and them. Halfmile has no connection with GISI or Yogi, and makes no money from them.

How do the UTM coordinates used on Halfmile’s maps work?
