that we failed to get off. Later, Brandegee and I rode up 
the canon and meandered and top T g f d the valley as far as the 
falls. Examined the Geology more carefully, found that nearly 
everything was metomorphic. Visible structure of the sediments 
ends with Comstock gulch and is observed again near the mouth 
of Lewis Creek. This is the mineral belt - or spot - for it 
extends only to the divides on either side. There is also a 
tongue of mineral bearing rock, mostly metamorphic, extending 
to the North West from Boven's gulch. There are doubtless 
dykes of trachyte running through the raetamorphic mesa, but 
they are not easily traced. The lodes are principally North 
and South and East and West. 
The river LaPlata is here a fine mountain turnout running 
In the bottom of a narrow and steep walled valley. Many 
small feeders or side streams come in tumbling down the steep 
slopes,forming almost continuous cascades. The slopes have 
aspens and rocks with occasional fine parks on the flatter 
parts by the Rio.
