Overview
As the name implies, The Apron is the large slabby apron of limestone that sits in front of the main headwall. At the top of the Apron there is a large treed terrace, which separates the Apron from the Headwall.
There are 30-40 climbs on the Apron, and this is where 90% of all the climbing in Marble Canyon takes place.
The guidebook by Lyle Knight titled "Central BC Rock" provides the best information on the climbing here.
It is possible to 4th class to the top of the Apron, but it involves some convoluted route findings - an adventure in itself.
The Routes
Gateway - Another Marble Canyon classic (climber: D. Dunlop, photo: A. Jones) Sisyphus - This is the most popular route on the Apron, and deservedly so - it's a classic multi-pitch limestone climb, with a bit of everything. Bring a descent size rack (at least one big cam), with more focus on the smaller sizes.
Gateway - This is a one pitch bolted climb, on the right side of the Apron. It's a very obvious beautiful slab. Although bolted, the climbing is still spicy - there's four bolts over 30 metres.
Topo - This is a topo for the Marble Canyon's Apron. I drew this in the 80's sometime, and for a while it was the only topo available for this area. Now Lyle Knight's guidebook "Central BC Rock" is widely available and fairly accurate. Although there are now a few more sport climbs along the bottom of the Apron, this little topo will still help you get by.
