FS 1070, located in the Ahtanum State Forest, starts towards the end of South Fork Tieton Road just before the Conrad Meadows Campground. The road crosses the South Fork of Tieton River and climbs steadily, apexing at approximately 5200 feet. This road does not receive much maintenance. There are rocky areas and washouts where a high-clearance vehicle is necessary. There are beautiful views of Mt. Adams to the south, and one of the area's biggest meadows harbors deer and elk in the spring and summer months. FS 1070 provides access to a 4x4 trail called 4W613 / Divide Ridge at the top. At about the 10-mile mark, the Forest Service has made some changes due to a huge washout. Thus, the road does not follow the map for about 3 miles. But rest assured, the GPX track included in this writeup is accurate. The road continues east through old forest burn areas that are rather beautiful before dropping down in elevation and ending at Tree Phones Campground on the North Fork Road. This road continues into the small town of Tampico just west of the city of Yakima.
