Part head scratcher and part Murphy’s Law in action as I checked out the Apple Map app and Google Earth to see the start of our Steel River trip. We begin with a short paddle up Santoy Lake from the put-in and then a 1200-meter uphill portage to Diablo Lake.

Here is what I found in the Apple’s Map app –

Image

It is not labelled Santoy lake – but rather Ogoki Resevoir ! Even worse, it is just one of three Ogoki Reservoirs which the Apple Map has labeled in NW Ontario!

On to Google Earth. It has the lake labeled correctly –

Image

but as luck would have it, the satellite image from 2006 includes a cloud over the very area I was hoping to take a look at – the portage from Santoy up to Diablo with its 100 meter altitude gain.

Google Earth is usually worth taking a look at to get a sense of the terrain but every once in a while all you get is cloud!

Try the map at the bottom of the page on http://www.comap.ca/

You can zoom out and up to the area you're interested in. There is no cloud on the image at that site, and you can zoom in incredibly close.

You sometimes have to wait for the images to load properly/hi-res when you zoom right in.

Someone here posted pics of the Diablo portage a few years ago. Maybe they are still hanging around.

Don't even bother trying to look at Diablo on a map. Nothing will prepare you for the pain and suffering. Best to go in with very little information or expectations.

Brad, thanks for the link to the Geobase map site! Great detail for the province of Ontario– and no cloud! I like how the elevation lines are provided. Here is what I found for the Santoy to Diablo stretch –

Looking at it I can see what Rob is talking about! We’re resigned to an “uplifting “ experience and looking forward to the reward - a great paddle down the Steel! Thanks again for your post with the annotated maps, Rob. To anyone interested, Rob's post can be accessed here -

We've got all your info on portages and campsites down on our maps.

Best satellite imagery for Ontario that I have come across is here:

http://www.giscoeapp.lrc.gov.on.ca/web/mnr/gib/basedata/viewer/viewer.html

Select "Map Layers" tab and check on the box for "Ontario Imagery" then check off the box for "Topographic Data"

Doesn't cover the whole of the northern part of the province, but the detail south of the Albany River is pretty good. There are a couple of voids.

With respect to the Diablo Portage, looks pretty ominous from the satellite images on the aforementioned site.

turtl, thanks for the little tutorial on how to go from topo to satellite view! The satellite image at the site you provide the link to seems to be identical to the image that Brad's link leads to. The only difference is that one superimposes the elevation profile and the other doesn't.

As for "ominous", I'm just glad we do not have a 75 lb. Royalex to carry up the hill! Our Swift Dumoine weighs in at 42.
