All appeared, however, utter confusion...

All appeared, however, utter confusion, such slight differences were there between the different mountains and ridges.

One peak alone showed itself above the general surface. It lay to the northward about thirty miles distant, and I recognized it as 'Gould's Dome,' from which I had previously remarked from the edge of the plains.

Hmm... thought I to myself. Was it because Blakiston was new to the mountains that he thought a mountain would look the same from another direction?

This traveller doesn't agree with either "expert". Viewing the scene from the same spot Blakiston stood I say this is the mountain Blakiston was looking at.
