No doubt about you Brian, you're good!
From Lake Elysia we climbed to the Walled Mountain summit again, then proceeded to the tarns on the Walled plateau for much need water, as it was at least 30 degrees. Then we head down across a nice pineapple grass field and up onto a very rocky boulder ridge leading roughly west. Crossing some very large rocks, then down the northwest side of these boulders to another grassy area, leading west and we come to a gap in a rocky knoll, which reveals a quite steep descent of approx 150 metres before you would need to travel through the trees then ascend at least 250 metres to the summit of Macs Mountain.
Due to the heat and the challenge faced on the boulders by my wife with somewhat shorter legs, we decided this rocky knoll would be our turnaround point.
Having descended off Walled and as we are passing the tarns on the way back to Lake Elysia, we got a fairly brief but very heavy thunderstorm.
Here's a photo of it getting ready to dump on us...

Turning around ended up being a good decision, the rocky boulders on the ridge west of Walled Mountain plateau would have been rather dangerous in the wet.
Your go Brian.
