Now I'm not sure whether I did it right when I was there.
But I think so...
When you finish the boulder hopping up the rock scree to the base of the cliffy bit, you look straight up and to the left a bit, and see the cairn that can be seen above the girl in photo "Mt Anne Crux" by Pedro above.
These small images of mine are links to larger files - if you view them in full size and scroll about, you'll see the detail I refer to.
This is the area as taken from above (after the climb) and to the right.

When you view the large file, you will see my pack just to the left of the wet spot.
As I remember it, there were two climby bits. The first was to get me to the shelf directly in front of my pack.
Then over that bit of rock and along to the ascent of the trickier bit.
When I was going up the trickier bit toward the cairn, I got myself wrong-footed, and because I had my day pack on (overnight pack actually, with minimal gear in it), I wasn't able to go up, or down. I had my left foot where my right foot needed to be, and because of the pack I could not rectify. So I took the pack off and handed it to my wife, then climbed down and reassessed.
To the best of my memory, this image reflects ther route I took. Same photo, but with dotted pink lines. Again, click on the image for a bigger pic.

In the larger image, the first circle shows where I left the pack, the second circle shows the trickiest bit of the climb, but that circle is showing a lump of rock I remember relying on a lot to pull myself up.
You come out beside the cairn, you can see that there is a fair bit of wear on the rocks in the area, indicating where the majority of people go.
After the climb, as mentioned the wet bit can indeed be hazardous if icy.
The route ahead is fairly well defined - see the cairn to aim for. The bigger pic shows the cairn in the big gap. Pretty straightforward.

The other side of this cairn looks like this - you can see the track and cairns.

So it is not impossible, but you do need to be confident and sure of yourself. When you get there you'll know. My wife is 5 feet 1 inch, and she went up, so it can't be too bad.
Even if you don't make it to the summit, you will still have a magnificent view...


More on topic - rock-climbing situations. I have recently returned from scaling Thetis from the western / northwest end, as well as some other lumps of rock in that area, not least of which (as far as rock climbing goes) was Achilles Heel.
There is some pretty interesting rock climbig to be done there.
I did not find a marked route, nor did I expect one. I wandered around to the left and found a crevice, began climbing and got at least half way up before it started looking too marginal. So I retreated and continued round further. Found another crevice so up I went again, this time making it to the top. There are a couple of peaks on Achilles Heel, both about the same height (as we noted when we made it to the top). The first peak was the one we climbed, and the second appears to have a cairn on top. No matter, I am happy to call it "done".
When climbing rocks like that, you get the feel for whether you should continue or whether it is too risky.
Although I could have continued further in the first crevice, it didn't feel right, like it was going to be too hard to get down, that risk was starting to outweigh reward.
It's more a feeling - like you just know not to. Perhaps a self-preservation thing.
I spend a fair bit of time looking - picking out a route, looking at what appears possible.
The Chapman notes talking about coming down from Thetis toward Paddy's Nut talks of broken / fallen columns.
Note the size descriptions used.
Here's my interpretation of scales -
Sand
Stone
Rock
Boulder
Column
Mountain
That is, when he says columns, he means some pretty BIG rocks.
Bigger than boulders.
One piece of advice I can strongly recommend when doing walks that require a lot of rock climbing is to take some good rigger or gardening gloves, perhaps leather.
The rocks are very rough and abrasive - great for grip on the boots, but bad for skin on the hands.
My fingers were nearly worn through before I decided to sacrifice my Gore-tex gloves. Expensive, but worth it.
I should have known to take other gloves for rocks.
I do not know whether I would use the gloves going up the trickiest bit on Anne, but if my memory serves me right, I did have gloves on then.
Not good rigger gloves then, either. I should know by now.
But if the gloves are not a good fit and you need to rely on your grip through a tricky section, might pay to stuff them in your pocket for a bit...
Now, since we are talking rock-climbing, I would really like to hear how people go on Federation Peak.Like from what we've done, ropes or no ropes? Go or not? Will we find it possible or is it a different level again?
My guess is that it will be no worse than anything we have already done, except that the view below the feet will be several hundred metres more than I am used to on the "climbing" we have done...
Any thoughts?
