The routes described here are all on roads, so you can't get lost. They're easy to ski on, easy to follow.
From the parking area, you can either take the road going east, or head directly north up the tubing hill. They meet up in a few minutes.
If you take the road, it divides immediately outside of the parking lot. Another route goes straight ahead, but I'll be describing the route going on the road to the left.
It turns sharply left, and starts ascending. In a few minutes, it meets up with the top of the tubing hill.
About a mile up the road you'll reach the entrance to Granite Flat Campground, marked by a fee booth (for summer campers), a gate and a granite rock.
Granite Flat is a perfect area for beginning cross-country skiers to practice. Snowmobiles aren't allowed on the campground roads so it's nice and quiet and you can actually breathe clean air. The campground has a nice, large loop road.
Now, back at the road junction at the entrance to Granite Flat -- if you take the righthand road, you'll eventually get to Silver Lake Reservoir. There are some astounding views of Timpanogos, Box Elder Peak, etc, on this road. The road switches back and forth many times, ascending about 1000 feet before reaching the ridgetop and flatter terrain near the reservoir.
Further proof this area is used a lot - at the far north end of the reservoir there are even restrooms open for use. Ah well, it's still a beautiful day ski. The lake is surrounded by slopes of varying degrees -- if there's good snow, these are great for practicing tele turns.
