Guess that peak

It will be the subject of likely my next trip report. I don't think its an easy one, but I left the road in the image to make it easier. Bonus as always if you can tell me the trail I took the photo from earlier today.

3270 from Santa Clara Divide Road?

No, though you are in the right neighborhood. What map exactly do you get your elevations from when referencing peaks or "bumps"?

Foreground has to be Bear Divide. Point 3200 perhaps?

You are so close, yet so far!
3270 I call "Birthday Peak" because I climbed it with my wife and our friend on her birthday this year....But alas, 3270 is not the peak in either my photo or your well-positioned google earth screenshot.

The 1995 USGS series. 3270' was my best guess. I lose.

Elwood wins. You can see the Clara Divide Rd cutting its way along the west flank. And Bear Divide is the best spot to do cookies and burn-outs for all the Fast and Furious types carving up The Little Tujunga Rd on weekends... (aka the posters on this forum, right?)
Oh, the bonus should be pretty easy.

Where was I earlier today and can you name all visible peaks?

There is one familiar peak with an unfamiliar silhouette from this vantage point which threw me a little bit, but I still got 'em all.

Not entirely sure I've got the viewpoint right, but based on Nate's recent travels:

I was just gonna say that he's on Santa Clara Divide looking across Pacoima Canyon, but Mendenhall is the flat top near the middle. I believe the fire road junction is near Highline Saddle. So that would make the closer, rounded summit The Pinnacle. If I'm correct, then way in the distance, over the left shoulder of The Pinnacle, you can also see the flat top of Markham.

You are mostly wrong I'm afraid! And missing a few, too.

You are missing a lot, but everything you say here is correct.

Clearly you were on point 3650: 34.36023,-118.36489. I tell my fancy software to do this:

Code: Select all

./standalone --image /tmp/out.svg --width 2000 --radius 1500 --zfar 150000 --znear 1000 34.36023 -118.36489 $((110-30)) $((110+30))

and I get the attached.

CORRECT!

If I'm following correctly, your software generates the silhouette profile based on coordinates you feed it (wich is very cool) ....but then how did you first figure out my position? Good old-fashioned human visual recognition?

It would take a lot more work to automate the search; doable, but work. However, it makes it really easy and fast to walk around, looking at the terrain change. So finding the spot is pretty quick.
