ATHOL, Idaho -- For thrillseekers, the numbers are pretty impressive. Consider them:

KREM 2

This is an artistic rendition of what the "Aftershock" will look like.

* A 19-story fall.

* Top speed of 65 miles-per-hour.

* Three upside loops.

That's what work crews at the Silverwood Theme Park are in the process of assembling: a new rollercoaster called the "Aftershock."

The new coaster will stand 191 feet off the ground - by comparison, "Tremors," the park's existing wooden coaster built in 1999, only stands 103 feet at its highest point.

Disassembled right now, parts for the new ride required 50 truckloads to get here from Chicago. Silverwood purchased the coaster from a Six Flags theme park in Chicago.

Laid out from beginning to end the new ride has parts that extend a half mile; the equivalent of 10 football fields.
