Sabrina . . . first of all, mega-thanks for the "greenie"! And, to answer your question, yup the trail I took is sometimes (especially by the Forest Service) referred to as the Cherry Mountain Jeep Trail. It is extremely easy to follow.
Although the mileage to Mt. Martha is nearly twice as long for the Jeep Trail as it is for the route up from Rt 115, it only took me about 20 minutes longer to hike the Jeep route. It is a very gentle grade and you can make really, really good time!
