You should note in the Overview that Teanaway Peak is not an officially named summit on the map and therefore the words "Teanaway Peak" won't be found on the map for those who might look for it. The peak also goes by the name "Genes Peak." I'm not sure which is the primary name.
I've been told the first part of the name is pronounced as two syllables: "tea-ANN-away." I always say it that way, but haven't asked any locals. Are my friends & I right?
I like having a pronunciation hint in the text for ambiguous names. It speeds up reading for folks like me who have to hear everything in our heads as we read.
