As we descended from Lost Mountain we noticed that the route up the next 'GR' looked like fun. It was fairly steep with some nice scrambly bits. After reading a recent trip report we also suspected that this might be more than just a 'GR' and may actually be a named summit.
Mount Yarrow is an unofficial peak on the southeast end of Spread Eagle (Roche) Mountain. It looked pretty close from the summit of Spread Eagle and I thought maybe 15 minutes would cover the traverse time to its summit. As with most ridge traverses though, I underestimated the terrain that's hidden in its curves!
Before completing Nugara's alternate descent from Mount Gladstone, we enjoyed some more hands-on scrambling to the summit of North Castle. It was difficult to determine where exactly the high point on this bump was, but we probably got pretty close to the highest one, without climbing a tree.
After getting out the previous two days on an attempt of Commonwealth and then a great day on Nihahi and Compression Ridges, it was time to visit the Castle / Crown area again. Keith and I drove down to the Gladstone trail head as described in Andrew Nugara's scrambling book.
