Help! How to find 42N 135W on a map? (Page 2)

Lots and lots of excellent ideas. I keep thinking! ANY HELP IS APPRECIATED!!!

Here's the deal, and I'm totally giving my game away, but whatever ... YOU drive/hike there and start digging if you want.

A famous author in his new book gives 8 clues in 8 illustrations leading to a buried cache. He even posts a photo of it. So far no one has located it yet, despite his millions of readers.

I don't know if the clues are in order, but I know they are correct. (For example, in one illustration, there is Morse code on a tiny piece of paper, which spells out BASIN).

The clues, in the order in which they appear, and in brackets my best guess at meaning are:

1. California VESA 99-S [If you take the 99-S from the Oregon border, you will hit Vesa Creek Trail]

2. DFG [Department of Fish and Game--have searched fruitlessly for a station around there. Maybe there is a map or pamphlet or license I need to obtain from the DFG?]

3. 8-5 [I have no idea. DFG is open from 8-5? Interstate 5? 8 miles down from I-5 (which is also 99-S) is where you'd go to get to Vesa Creek Trail].

4. 45 POLICE [.45 police revolver? What would I need that for? To blow the cache case open? There's no exit #45 anywhere near there, and the nearest police station is in Yreka, but I can't figure out what 45 has to do with POLICE.]

5. 42nd St., Locker #135. [Vesa Creek Trail is at 42N longitude. Still trying to figure 135 out.]

6. 25 PACES EAST

7. BIG

8. BASIN [If the clues are in order and I've gotten this far, then the cache is 25 paces east of the big basin. And there is one around Vesa Creek Trail.]

Any takers? I am totally obsessed with this
