Sourdough Moe Posted September 13, 2018 Share Posted September 13, 2018 im looking with an online map for an area that an old known miner from the 70s would go. he would get droped off by dog sled in spring than walk back in fall. does this look like a dam for a sluice or a dam to catch fish????

GB_Amateur Posted September 13, 2018 Share Posted September 13, 2018 I don't think the photo gives enough info, but you likely can find that info yourself. Some questions to ask: 1) Is this a gold producing area? (I assume, based upon the intro, you already know this.) 2) Is this a commercially viable fishing spot? 3) Would the governing wildlife organization even (in 1970's) allow damming a creek to enhance harvesting fish? Would they allow today? If they did in the past would they require the dam be removed when the permit expires. (You could also ask this question if a dam was built for precious metals recovery.) 4) Is the location sufficiently remote (or was it in the 1970's) to require dog sled access and provide secrecy/privacy for the miner in question? There may be some other clues I'm not sufficiently knowledgeable to decipher, such as: "If you were going to dam up this creek for gold recovery, is this the right spot for the dam?" GL with your quest! Link to comment Share on other sites More sharing options...
LipCa Posted September 13, 2018 Share Posted September 13, 2018 I see dredger tailings in the photo so it must be a gold area. Doesn't look like any mining in the river there. If more of the surrounding area was shown, might lead to a conclusion. Link to comment Share on other sites More sharing options...
Steve Herschbach Posted September 13, 2018 Share Posted September 13, 2018 Beaver dams. Whole series of old ones there, and this is the newest. I am not seeing the dredge tailings (looks natural to me) but that might be a trail or ditch line angling down from upper right. Link to comment Share on other sites More sharing options...
Sourdough Moe Posted September 13, 2018 Author Share Posted September 13, 2018 That does look like a tailing pile where the pile of rocks are and damning it to make it deep enough to dredge looks like its a newer spot than from the 70's Link to comment Share on other sites More sharing options...

LipCa Posted September 14, 2018 Share Posted September 14, 2018 you are right Steve. now that we have a larger pic. if you enlarge the first one and look in the lower right corner, it looked like tailings. but it must have been the river. Link to comment Share on other sites More sharing options...
GB_Amateur Posted September 14, 2018 Share Posted September 14, 2018 Is it possible to find (e.g. government archived) LIDAR pics of that area? I don't know how likely it is for vegitation to overgrow tailing piles in that climate, but if such happened I expect LIDAR would reveal them.

I have both taken and studied many aerial photos of Alaskan stream valleys Link to comment Share on other sites More sharing options...
