On the first day of every month the City Daily Blog community host a theme day. Every month the theme is different.
The theme day for September 1st is "Big"
I happened across this scene while working in the hills north of Carlin, Nevada (Carlin is a town just west of Elko).
This is called a haul truck, this particular model is by Caterpillar. It is approximately 44 feet tall at the highest point (when the dump is raised). It has 15 foot tall tires and a 240 ton payload.
The job of this truck is to haul unprocessed earth, from the open pit, to a nearby processing plant where gold, other ore and minerals are extracted. There are many trucks like this in the hills nearby.
By comparison this is a medium sized haul truck. I have encountered trucks in this area that actually dwarf this one.
