A Crag Guide gives an extensive view of all sub areas and climbs at a point in the index. It shows a snapshot of the index heirachy, up to 300 climbs (or areas) on a single web page. It shows selected comments climbers have made on a recently submitted ascent.

At a minor crag level this should be suitable for printing and taking with you on a climbing trip as an adjunct to your guidebook.

1. The Central Scrutinizer 21 routes in Crag

Mostly Sport

Long/Lat: -100.476534, 25.949287


This is the large clean buttress on your right after you pass the Pool Area and fenced off base of "The Virgin Canyon". It runs until the big tree against the wall on the aqueduct.

Access Issues: inherited from El Potrero Chico

Most of the climbing here is in a State Park and there is no fee to enter. Please help maintain a clean environment in order to help maintain these privileges.


Step off the road, over the aqueduct. You could, if you had actually driven to EPC (or up to the Potrero from camp) actually belay most of these routes from your car.

11 Mr P. Mosh 5.10b Sport 26m, 8
12 *** Gringo Disco

Long and sustained. Don't confuse the anchors for "Mr. P. Mosh" as part of the climb -- though they can be very useful for rappel to get down with a single rope.

5.11b Sport 50m, 14
13 Central Scrutinizer

Follows old rusty bolts, with exciting runouts. (Rap anchors 1/2 way -- or treat as 2 pitches.)

RouteGradeStyleSelected ascents
17 Monster Truck

Looking up into the Potrero from the camping area, there is an obvious steep ridge line up the right side of the Potrero -- that's Monster Truck, the whole ride line.

Do the first two pitches of "Quick Draw McGraw", then continue up the ridge following the path of least resistance when the ridge looks harder than 5.9.

Lots and lots and lots of pitches, with generous chunks of 3rd class, too.

5.9 X Trad 1800m
18 Bazookaed in Monterrey

Climb the large corner right of "Quick Draw McGraw".

5.10c Sport 3
