US-20 on the west side of Dubuque, then Asbury Road. This page puts Iowa DOT's plow trucks, 511 Iowa's cameras and its closure and crash reports for that road on one map, refreshed every minute. The resort's own Sundown daily snow report covers the mountain itself.
Iowa DOT trucks reporting a position on US-20, US-52 within 36 miles of the base, or on any road within 12 miles. A pin is a position, not proof the road is open or bare. Trucks not heard from in 60 minutes are faded.
Positions come from the trucks' own GPS, through Iowa DOT, and refresh here every minute. "Last reported" is the truck's time, not ours.

A plow pin is where a Iowa DOT truck was when it last reported, with the route and mile the DOT attached. It says a truck was there. It does not say the road behind it is bare, and it does not say when the next pass comes. The DOT's camera, where there is one on US-20, US-52, shows the surface itself. The closure list is 511 Iowa's own feed, read every five minutes and converted to the format MileCheck uses for every state. A quiet list means 511 Iowa has posted nothing for these roads, which is different from a road being open.
The 12 miles ring is the search area for trucks and cameras. A truck reporting on US-20, US-52 is kept out to 36 miles from the base, the stretch a driver is actually on; anything inside the ring is kept whatever road it is on, so a truck on a side road near the base still shows. The resort's own Sundown daily snow report is the source for snowfall, lifts and the parking lots.
The map shows every closure and crash 511 Iowa is publishing on US-20, US-52 as a red or orange marker, and the list under it says when the DOT last updated each one. No marker means 511 Iowa has not posted a closure, not that the road is open. It reloads every five minutes. For the official word, open 511 Iowa.
On the map, as blue truck pins. Each is a Iowa DOT truck's last reported GPS position, with the route and mile the DOT snapped it to, how long ago it reported, and the material it is spreading where the DOT sends that. A pin tells you a truck was there at that moment. It does not tell you the lane behind it is bare. Trucks that have not reported in an hour are faded and say so.
