[Current state of landform shapes in the valley end after an initial round of filling and sanding.]
I thought I'd try my hand at a little landscaping on the EVRR. To get started I decided to have a go at defining the landforms in the valley end.
Before starting I wrapped the mountain end in a garbage bag and put masking tape over the track where I'd be working.
Voids in the elevations were filled in with scrap foam blocks and gaps were puttied with a non-volatile wood filler. Once dry, the Dremel was carefully used to grind and smooth the foam into a seamless shapes. There's a lot of dust, so I wore a dust mask and used the Shop-Vac to make regular debris cleanups. A few more rounds are going to be needed before the landscape comes into focus.
