Apologies for not getting back sooner, but thanks.
Building the canyon was one of the most rewarding modelling projects I have done.
For several months one rainy, cold Oregon winter, I cranked the heater in the garage,
brewed a pot of coffee, and turned on some tunes and blissfully carved away.
One of the shortcomings of the 8' long module,
was that I didn't know what my goals for the layout would be.
The canyon section was built to On30 standards I found online
(might have been the Texas Outlaws group),
but I didn't realize at the time that I would get into photographing the models.
One of the standards of the modular group,
was to place the center of the track six inches from the front edge of the layout,
which works well enough for operation, but does not work well for photography.
Here is an early picture of the canyon with the suspension bridge,
showing the lack of foreground:
