Thurman Flat (Sport Boulder)
BETA PHOTO: The northeast face of the boulder
Thurman Flat offers steep, fingery and powerful climbing on well protected sport routes. All the routes are located on one large boulder composed of a polished conglomerate rock. Although short the climbs will test your finger strength. The climbs can be dusty depending on the time of year.
Although the climbing here is not the best in the area it is still a worthwhile destination if your are comfortable climbing 5.12a+.
Drive Highway 38 from Redlands heading east. Drive through Mentone and follow the 38 past the Ranger Station (pick up an Adventure Pass here if you don't have one) and continue along the 38 for 3 miles until you see a sign for Thurman Flat Picnic Area on the right. Park here and follow the trail down to the river where the large boulder can be clearly seen on the other side of the river.
Take care crossing the river (a fallen tree can be used in high water conditions).
Weather station 1.7 miles from here

This is a small but worthy local area with technical climbing on slick rock. As mentioned a great area for those climbing 5.12 and up.
In addition to the roped climbing there is some decent bouldering in the area, but watch out for broken glass!

Still a good climb for some practice, hadn't climbed it since 2010 looks like some new routes were added
As for the poison oak watch out its still there near a popular hold in the middle of the east side, went right into that one.
