0.1 Patrick Creek Road (located on the left immediately after
crossing the bridge)
The Patrick Creek Bridge marks the end of the mantle rock and the beginning of another section of ocean crust, the second of three that you will drive through on this tour. 1.1 The turnout on the right has a trail down to the river. Just after the turnout and along the road cut on the left are the flat surfaces of ocean sediments that were deposited directly on top of the ocean crust. All of these rocks have been turned up on end. You have just driven from the bottom of the ocean crust at Patrick Creek to the top. These sediments are believed to have been deposited in a very deep ocean setting and the fine silts were compressed into flattened layers as other sediments accumulated on top of them. 1.5 Road Straightens - opportunity to pull over and let traffic pass 2.0 Large turnout on the right overlooks river 2.1 Bridge 2.2 Passing Turnout - pull over to let faster traffic pass
2.9 Lehman Bridge:
3.3 Siskiyou Creek Road (right) 3.8 Short passing lane begins - pull over to let faster traffic pass
4.1 Large turnout on right with call box. 5.0 Turnout - pull over to let faster traffic pass. Other turnouts are at 5.3, 5.6, 6.0 5.9 Exit ocean crust. From this point the road leaves the ocean crust and enters ocean sediments. You will drive through this type of rock until you reach the last section of this tour near Grants Pass, Oregon. This doesn’t mean that the sediments are 40 miles deep. At this point, the rocks of this region arc northward and you will be driving parallel to the ocean crust, which will be on your left. 6.1 Idyllwild was named after a motel located here in the early history of Highway 199. The small rock foundation where the gas pumps sat can be seen near the road on the left. This site is now the location of a California Transportation (CalTrans) Station. The old Idyllwild Motel is seen below when Highway 199 was still a gravel road.

8.3 Turnout - pull over to let faster traffic pass 8.4 Turnout 8.9 Turnout
9.1 Volcanic Ash (left): A small seam of white colored volcanic ash can be seen cutting diagonally across the road cut (picture above left). This ash is believed to have come from a small chain of volcanic islands that were once located about 15 miles off the ancient coast of this region 150 million years ago. Volcanic ash is one of the easier rocks to identify on the gravel beds of the Smith River (picture above right)
9.3 Oregon Mountain Road (left) is a segment of the old 1922 Highway 199 that climbs over the mountain above the Highway 199 tunnel about two miles ahead and returns you back to Highway 199 about five miles ahead. Most of this route is paved but you should expect to encounter road hazards such as fallen rock and other debris after rain storms. The road may be closed by snow in the winter. The picture above shows the switchbacks above this intersection as you climb to the pass. In the middle, right background is Broken Rib Mountain and to the right of that is Wounded Knee Mountain. The mountain on the left is in the Siskiyou Wilderness. 9.5 Passing lane begins. Use the right lane to allow faster traffic to pass. 11.3 SET ODOMETER TO ZERO at the entrance to the rest area on the left before entering the tunnel
