The nomenclature for these mountains is a bit hazy. I have always known the two "middle" Truchas peaks to be known as Middle Truchas and West Middle Truchas, respectively. I have heard of Middle Truchas being referred to as "Medio Truchas," but "Medio" is simply Spanish for Middle.
In the classic book "The Mountains of New Mexico" (published in the 70's), the two mountains are referred to as Middle Truchas and West Middle Truchas respectively. I have always been very fond of this book and have thus adopted its nomenclature of these mountains. After all, it was this book that introduced me to these beatiful peaks.
To me, it makes more sense to call them "Middle" and "West Middle," as calling them "Medio" and "Middle" seemed a little confusing--kind of like calling "Red Mountain" (CO) "Rojo Mountain."
The confusion is compounded by the fact that the maps seem not to recognize a distinction between what I have called "Middle" and "West Middle." They just lable the whole area "Middle."
BTW, where did you see them referred to as "Middle" and "Medio"?
Interesting debate, anyhow.
Do you have a picture of South Truchas that you would be willing to let me copy to my computer and use? My dad and I climbed South Truchas years ago and he is 91 now. I would love a good picture of South Truchas that I would be able to keep, and give credit to you of course.
