Mid-week escape: Little Arethusa - Mt Arethusa [ - Mt Rae, potential for the future]

Arethusa has been on my list for a while; it's known as a pretty short scramble. Managed to sneak out from an office by lunch and was at the trailhead around 1pm.

Quick stats: 7.7 km with 987m gain, 4:40hrs car-to-car

Little Arethusa (2:15pm / 15mins):
Started at 1:15pm; very straightforward; though missed the main trail, took left too soon, as was using someone's GPS track, no bushwacking, followed a game trail through sparse woods.


Mt Arethusa (4:20pm / 20mins):
Connecting ridge is where it gets interesting. Had to turn around almost at once, as came across of a drop; but then was simply finding way through ledge on the east side of the ridge. It goes all the way to the lowest point on the ridge, about 60-70m loss.
Moreover, while I hadn't been able to find ANY report on the traverse, apparently people do it from time to time, as there are at least 3 cairns on it.
Just about 50-100m from there is a notch with a drop; unless you bring a rope and rappel, it's damn exposed down climb.
Had to loose another 100m of that.
Spotted someone's track further on the slope and simply followed it. Was just an easy slope, ended up with a couple chimneys (moderate scramble) and simple exit to the ridge.


Descent:
followed a track I had on my GPS, plus someone's footprints. Started as a gully, then narrowed to a chimney and ended up as a crack.
The only thing one needs to know about it: there is an old sling on a choke stone in the middle of the descend.
Should've stayed on the ascent line.
Back to car at 5:55pm.



Potential for Mt Rae:
Was looking at the map before the trip and guessing whether it goes. Was thinking to continue but was a bit short on time. I guess a full day is needed for that.
At the same spot where the descend "gully" started, there is similar one on the other side, toward the Ptarmigan Cirque. It wides with loss of elevation and becomes a pretty wide ledge. The only thing wasn't clearly visible whether there is a descent down climb off the ledge to the scree below. I'd say there are two options:
1) going in that direction, bring a rope just in case for short rappelling, 30m should do.
2) try another direction, i.e. Rae - Arethusa, didn't see any issues for the up climb there.
