Find Your Car, Then Fry Sauce
Okay. Last lesson your phone died mid-canyon in the story, and you still found your way out with lines on a map. That felt good, right? Now we're taking all of it, every piece from this whole module, and pointing it at one specific, extremely motivating target: your car.
Because here's the truth about triangulation. Nobody does it because they love drawing lines on paper. They do it because they're standing somewhere and they need to be standing somewhere else, usually where the snacks are.
So today's the day we go from "I understand the concept" to "I can actually do this."
The setup
You need three things you can identify on your map, spread out enough that they're not clustered on one side of you. Peaks work. A radio tower works. A saddle between two hills works if it's distinct enough to point at with confidence. Your car does not work, obviously, because that's what we're solving for.
Stand where you are. Pick your three landmarks. If you can only find two, two is fine, we've done that already. Three just tightens things up and gives you a gut check, because all three lines should cross in roughly the same spot. If they don't, something went sideways in a bearing or a plot, and now you get to go find your mistake, which is Low Key my favorite part of teaching this. Not because I like watching people struggle. Because that's exactly how it sticks. We did it wrong on purpose two lessons ago for that same reason.
Take your bearings
Hold the compass flat, out in front of you, level. Point the direction-of-travel arrow at your first landmark. Turn the bezel until the red needle sits inside the outline, the orienting arrow, whatever your compass calls it. Read the number.
Say it out loud. You know the drill by now.
Quick aside, and I mean this one seriously: keep metal away from the compass while you're doing this. I once had my sibling Amber hold hers flat right up against a big steel water bottle on a hike, trying to get a reading, and the needle just spun like it had opinions. Took me a solid ten minutes standing there to figure out what was going on. Watches, pocketknives, water bottles, your phone. All of it can pull the needle off. Nobody warns you about this when you buy the thing. I'm warning you now.
Do the same for landmark two, and three if you've got it.
Adjust and plot
Your compass is already doing the declination math for you, since we set that up a few lessons back. So the number you read is the number you plot straight onto the map, no fudging, no doing math in your head. That's the whole point of adjusting it in the first place.
Line up your baseplate on each landmark on the map, rotate it to match your bearing, and draw the line back toward yourself. Do all three. Where they cross, or where they make a tight little triangle instead of a perfect point, that's you.
Mark it. Now orient your map to the actual terrain around you, the way we talked about back at the start of this whole thing, my dad Craig's trick that finally made maps click for me. Physically turn the paper until it matches the hill in front of you. Now look at where your dot is relative to the trail, the parking lot, the trailhead sign. Now you know which way to walk.
That's it. That's the whole skill. Everything else in this course has been building toward that one moment of "okay, walk that way."
A plain caution
If it's getting dark or weather's rolling in while you're doing this, don't get so absorbed in the lines that you forget the actual sky above you. Take the bearing, get your direction, and move. I've been caught coming down a canyon with a dead phone in an afternoon storm and the only reason I wasn't guessing at that point was a dry map in a ziploc bag. I'll bring that up again before this course is over. Probably more than once.
My honest opinion here
The cheap baseplate compass you bought for this class is genuinely the right tool for this job, not a starter version of the real thing. Fewer parts, nothing to fuss with, you just read the number and go. I own a nicer sighting mirror one. It sits in a drawer. This is the one in my pocket.
Before next time
Find a flat, boring spot near your house, a park, a parking lot, whatever, and practice this three-landmark triangulation on purpose, even though you already know where your car is parked. Getting it right when nothing's at stake is how you get it right when something is.
