Where on Earth? - July 2017

Where on Earth - July 2017

Clues for July 2017:

1. This mountain peak offers striking views of numerous linear dikes that appear to radiate from the mountain, which is part of a range that straddles two states and has a biblically bloody name.

2. The mountain is the remnant of an igneous stock composed mainly of quartz syenite and monzonite, which intruded roughly 25 million years ago into existing sedimentary rock layers. These layers have since eroded to leave part of the stock exposed.

3. At about 4,155 meters, or 13,632 feet, the mountain is not among the more than 50 “fourteeners” in this state, although it is the easternmost 4,000-meter-plus peak in the U.S., and it’s the taller in a pair of similarly named adjacent peaks.

 

 

Name the mountain and its host state.

Answer: At 4,155 meters, West Spanish Peak is the taller of Colorado’s two Spanish Peaks, part of the Sangre de Cristo Range that extends into New Mexico. It is a remnant of an igneous stock composed mainly of quartz syenite and monzonite, which intruded roughly 25 million years ago into now-eroded sedimentary rock layers.
