First off, I am new to the investigation and this community. I have a lot of catching up to do. If my posting about things that are old news to the rest of your are inappropriate clutter, let me know and I will refrain. But I'm curious how some of the early puzzles were solved so that if I run into those encoding techniques again, I'll have an idea of what to try.
Trying to catch up on my investigation, I ran into an old aerial photo of El Cosmico, a lodging area with trailers, tents and teepees in Marfa, TX, with a QR code on it, which my trusty Barcado app decoded.
Did anyone go to El Cosmico in Marfa? Was anything found at that location?
The QR code itself was just a series of numbers 124 characters long:
7353028343028343027353029343022313130263730243830283430263031331303620343820383420373620313132203439203537203438203438203537
I experimented with breaking this into two digit sequences to see if an obvious code pattern would emerge (why? 2 and 4 factor into 124, 3 doesn't, and I'm used to using two digits (ASCII) and 4 (Unicode) to represent other characters), and one of the things that jumped out at me was the sequence is a palindrome - the same backwards and forwards.
The second half looked promising. I've done work in digital publishing, so I know that 20 is the ASCII code for a space and that the digits start with a 3, so this looks like another series of numbers:
31 30 36 20 34 38 20 38 34 20 37 36 20 31 31 32 20 34 39 20 35 37 20 34 38 20 34 38 20 35 37
Reduces to 106 48 84 76 112 49 57 48 48 57.
Assuming these want to be (ASCII) letters, I converted from decimal to hexadecimal and looked up the values in the Windows character map:
6A 30 54 4C 70 31 39 30 30 39
ASCII:
j0TLp19009
gibberish. OK, but we started with a palindrome, so what if we flip it?
90091pLT0j
gibberish.
So questions are: 1) What am I missing? And, 2) Was anything found at Marfa?
