A much harder alternative is to continue another 1/4 mile up the wash and ascend the scree slopes on the north side of the ridge, following ocassional cairns. Unless you are looking for a massive cardio workout, this route is not recommended. This route eventually merges with the ridge route once the top of the ridge is met.
Continue up the ridge, following the well defined use trail. It will switch back from time to time but remains steep most of the way until just before you reach Bedsprings Camp
Bedsprings Camp: 7075ft 36.71743 N x 117.99935 W
Here you will find the remains of an old mining camp replete with an ancient rusty set of bedsprings. There are about a half dozen nice flat campspots to be found here.
From the camp, continue heading east for about 1.25 miles to the obvious large col between Inyo and Keynot. Mt Inyo lies about 2 miles to the north; stay on the west side of the scarp, bypassing 2 false summits until the true summit is acheived
