One thing worth taking note of here is that the 1978 Zodiac letter is almost certainly a hoax. For one thing, SFPD told the FBI that it was, and they excluded it from their profiling attempt. But more interestingly, SFPD later did DNA testing of the letters, and found that all the authentic ones had no cells, and that they were consistent with the stamps having been moistened with tap water, whereas the 1978 letter actually generated a DNA profile. For a bunch of reasons (including SFPD's communications to the FBI), that letter was probably written by Inspector Toschi.
It's a similar situation with the Sierra Club postcard that you seem to be referencing. That one also appears to be a hoax, as it seems to have been written by someone unfamiliar with other Zodiac letters that hadn't been published in the press at that point. But even more interesting,ly, Tom Voigt says that in 1999 a retired investigator told him that they knew who had hoaxed that card, and he'd confessed to doing so. So the hoaxer can't have been JJD, as he was never an investigator in the Zodiac case. For my money, that was Toschi too.
If it was a hoax, then the Incline Village line of sight due west (“peek through the pines” “pass Lake Tahoe areas”, “around in the snow") ended up being a pretty good clue to finding Donna Lass' remains.
