Whether or not you believe this interpretation, it is vitally important that you consider the design of the Monticello card, mailed by the Zodiac Killer on July 13th 1971. This postcard did identify the burial site of one of Zodiac's previously claimed victims - that of Kathy Snoozy - who the Zodiac Killer claimed alongside Debra Furlong, when he added August to his chronological victim count in the "Dripping Pen" card on November 8th 1969. The Monticello card (like the Pines card) contained a message of pasted newspaper text, reading "Near Monticello Shought Victims 21 ...... In The Woods Dies April". This text was identifying the name of Kathy Bilek by using the namesake of one of his previously claimed victims.
The Monticello card contained pasted newspaper text, never directly named Kathy Bilek as the victim he was claiming, and gave us directions to the burial site of one of his previously claimed victims (Kathy Snoozy). The Pines card used the same template by failing to mention the name of Donna Lass (but insinuating her as the victim) - and may have used the newspaper cuttings to direct us to the deposition or burial site of the Lake Tahoe nurse, just like he did with Kathy Snoozy at Monticello. If the Zodiac Killer was the author of the Pines card, then he retrospectively claimed the lives of Donna Lass, Kathy Snoozy, Debra Furlong and Kathy Bilek months after their murders. He would retrospectively claim the murder of Cheri Jo Bates also. We may now have two pasted postcards, both possibly giving us directions to the remains of a murder victim claimed by the Zodiac Killer.

Based upon the measurements of the San Francisco Examiner's pages, I calculated that the "Sierra Club" headline measured about 1.65 inches in width, which was the same as the "Sierra Club" pasted on the Pines postcard. Curiously, the remainder of the article (not shown here) contained the word "areas" twice - that based upon the font - were not used in the Pines postcard to create the "pass LAKE TAHOE areas" phrase.
