Eagle Creek Map Error!

Post by Splintercat » April 10th, 2012, 6:54 pm

Chatting offline with another PH'er, and noticed that Metlako Falls is incorrectly identified on the USGS map! Check it out:

Okay, so maybe this is old news and I've been checked out... but it should be mapped just above the junction (or nearly at the junction) with Sorenson Creek, right? The falls marked "Metlako" is actually the low falls that appears in Jamey's epic winning photo of the lower gorge. Odd that Sorenson Falls isn't even mapped -- it's quite substantial, and year-round, too.

Well, I guess those USGS cartographers are human, too... ;)

Oh yeah, I've seen this one... However, not to give too much away, that is the approx. location of the weeping wall.

Sorry, but isn't it marked on the map right there, just right of center?

Tom, yeah, I've noticed that too. Not too unusual to have errors, though, and there's too many to count and just seem to go on forever.

Here's a pic I took of Metlako last year and my GPS track showing where I took the photo from. (I seldom correct my camera's time from or too daylight savings so it's an hour off)

a lot of the maps we use today are old technically, created by aerial surveying. Are there any plans to update the usgs topo maps?

@Rad -- sorry, I should have said that it's on the map, but in the wrong spot...

The current generation is called US TOPO and Oregon's were updated in 2011.

Here's a link to the spot we're discussing

USGS Store

Unfortunately, the methodology has been changed and trails (among other features) are not being included at this point. See this thread New US TOPOs & historic topo quads now available for Oregon

You can also always be a helpful citizen and report errors you see on the map :D

See question 2 for details.

CampinCarl,

Don't waste your time reporting errors. the USGS 2011 Mt. Hood Map is horribly incorrect (SplinterCat and I discussed this offline). I sent a polite email to them with plenty of caveats that I certainly may be out of my element but it seems like a number of mislabeled items (leuthold coulior at illuminsation saddle, camp blossom [timberline area] located directly west on the ridge from ill saddle..Sandy Glacier Headwall is located at Leuthold Coulior, triangle moraine is over in no-mans land by newton clark glacier, across from white river glacier). They sent a semi-snippy response pointing out a few instances where I pluralized a name (leutholds coulior, castle crags, etc) and said someone would be getting in contact with me.

twas perhaps 4-5 months ago..

:( Sorry for your unpleasant experience. I work in the Geographic Information System (GIS) field and I've met the USGS Geospatial Liason for Oregon. In a talk I attended a couple of years back, she was part of the panel that discussed the agency's desire to improve the accuracy of the GNIS. I'm not sure why it would be poo-pooed when someone actually wants to help :?
