This fall I'm hopeing to head into the Kopa Provential Park in Ontario for a solo. I was looking at caltopo maps and on Kashishibog Lake I found something I've never seen on any map before and was wondering if anyone could help indentify them. The "ridges" are at GPS cord of 49degrees N 49. minutes 11 seconds W 90 degrees 00 minutes 69 seconds. I thoght they might be fire breaks roads but then there should be a road to the next one. Possibly rock ridges, I'm at a lost. Any suggestions??? FRED

Maybe check the co-ordinates again can't have 69 sec.

Are you referring the hash-maked area, bog or swamp? Lines, what color?

I use gmap4 : https://mappingsupport.com/p/gmap4.php
On the home page click to start gmap4 and display default map.

The best three options are are h, t2 and t5 from the drop down in the top right corner of the map.

Using the h- aerial Google Hybrid option the there are at least 12 ridges visible, some of which are over 2 kms long crossing the land and bays in this area. However, they are not visible on either of the other two views, t2 and t5.

I find the t5 Topo Canada option to be the best when planning. When you zoom in on the map each level of zoom is re-drawn in clearer detail. This is unlike the t2 and h option which just make the underlying map or photo larger.

A mystery to me what these features are. They clearly look like East-West ridges, but they don't appear on the topos... and I've been canoeing in the Wabakimi Area for 11 years.

Are we talking about the horizontal ridges across the peninsula in the center of this sat image?

Didn't know you were looking at Sat/Aerial images.
Bing Maps, note the building and dock on the island.

Probably glacial formations, Moraines are deposits, Aretes are erosion. They can form in parallel formations.

those are strange. my guess would be eskers but i have never seen any like these. edit- agree with butthead, glacial deposits.

Aliens ??

thanks for the replies, yes thefourofus those are the lines I was looking at,kinda thought they were rocky ridges but haven't seen them on other maps in this area of Ontario. Last year I was about 1/3 the way to them and started having problems with my shoulder and wrist and decided to turn back, hopefully I'll get to them this year. Aliens always make crop circles not lines. FRED

Butthead nailed it again. I had no idea so I went to the Google.
They are called lateral moraines. Lateral moraines are parallel ridges of debris deposited along the sides of a glacier. The unconsolidated debris can be deposited on top of the glacier by frost shattering of the valley walls and/or from tributary streams flowing into the valley. The till is carried along the glacial margin until the glacier melts. Because lateral moraines are deposited on top of the glacier, they do not experience the postglacial erosion of the valley floor and therefore, as the glacier melts, lateral moraines are usually preserved as high ridges.

There I learned something for the day!

Thanks! I just learned something too!

I would think they must be some very large ridges of rocks to show up that plain. Mayhaps there's some gold nuggets laying around? I do know theres an old gold/silver mine shaft about 8-10 miles away [as the raven flies]. Hopefully get to see them this fall. Thanks for letting me know what they are. I see some of them appear to run right into the lake, might be a good spot to jig for walleyes? FRED

If you look them up on Bing Maps you will get images form overhead and angled, also seem to be a different series of images from Google.
They do not seem as pronounced there, looking more like rows of rocks like 1800's farm rockwalls.
