SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 69 



Standing up high above this desolate region is the great rocky peak of 

 Mt. Chiriqui, which I believe I am the only man to have climbed. The 

 summit is a towering rock, its extreme point so sharp and narrow that I had 

 to straddle it. Under one foot was a sheer fall of some 900 feet, under the 

 other a sharp slope of 600 or 700. I found no signs of any previous ascent, 

 but left two records of my own visit. From the top I looked down on the 

 waters of the Caribbean Sea and of the Pacific Ocean, seeing distinctly the 

 indentations of both coasts. To the west I could see the Costa Rican 

 Mountains, and to the east stretched an ocean of small peaks. My aneroid 

 registered 11,500 feet. 



This zone seems to be representative of the several boreal life 

 zones recognizable in No'rth America, but its exact relation to them 

 remains to be determined.
