In previous articles I wanted to evaluate how accurate the Pines postcard was in identifying the location where the jawbone of Donna Lass was discovered on December 31st 1985 near Yuba Gap. Because the phrase "around in the snow" was inverted 180 degrees and we had a punch-hole in the postcard that many believed was her burial location, I decided to flip the postcard upside down. What we notice from here is that the center of the punch-hole is now west of the "Sierra Club" pasting, with the center of each being in perfect horizontal alignment. The postcard used by the author was a USPS Abraham Lincoln 4 Cent Blank Postcard that measured 5 9/16 by 3 1/4 inches (5.56 by 3.25 inches).
So using the map scale of 6.4 miles to the inch, used by the Zodiac Killer when mailing the Mount Diablo Phillips 66 map in 1970, I measured the distance between the "Sierra Club" pasting and the center of the punch-hole. It measured 2.19 inches, which I multiplied by 6.4 miles to the inch, to get a distance of 14.02 miles. Drawing a perfectly horizontal line westwards from Clair Tappaan Lodge, the 14.02 miles ended just above Interstate 80, directly below the eastern edge of Chubb Lake (in the top right image shown below). The jawbone location was only approximated as one mile northeast of the I-80 at Yuba Gap (in the top left image shown below). I then had to calculate the distance between the location identified by the Pines postcard and the actual (but approximated) location of the jawbone. The remains of Donna Lass could have been deposited or buried anywhere in California or Nevada, yet the Pines postcard identified a location only 997 meters (or thereabouts) from the actual location of the jawbone (if my interpretation is correct). This can be seen in the bottom image below.

If I had drawn a line on Google maps from Clair Tappaan Lodge to the estimated location of the jawbone, it would have measured 13.62 miles, so from a distance standpoint, the accuracy was 97.1%. The angle deviation was approximately 2 degrees. In other words, there was an error of 997 meters over 14.02 miles. But was the Pines postcard created with these calculations in mind, or was it purely accidental? The phrases on the postcard such as "pass Lake Tahoe areas", "Sierra Club", "peek through the pines" and "around in the snow", pasted onto an advertisement of Incline Village, with a punch-hole added to the postcard, does lend to the notion of an author giving us directional markers. That is why I decided to measure the distance between Clair Tappaan Lodge (Sierra Club) and the punch-hole.
The punch-hole may have denoted the burial site on both sides of the postcard, with the letter "d" of Zodiac and initial "d" of Donna positioned over the crosshairs, and the Abraham Lincoln stamp, initials "a" and "l" positioned horizontally to the right. This gave us "d", "a" and "l", the initials of Donna Ann Lass originating from the punch-hole. .
