A HEAVY DOWNPOUR 
was surmounted by golden and red streaks of wonderful 
vividness. Later, over the great natural gateways, the 
sky formed itself into concentric arches of blazing yellow 
and red, rendered intensely luminous by contrast with the 
heavy, black clouds which were fast collecting overhead. 
No sooner was the sun well above the horizon than we came 
in for a heavy downpour. 
The temperature had been higher (minimum 60° 
Fahrenheit) than usual during the night, and heavy. 
The elevation of our camp was 2,030 feet above the 
sea level.
