There are a few interesting peaks on Lytle Ridge (east of Lytle Creek) and an ex-HPS Peak. None seems difficult, but this is exploratory.
Two of the peaks have summitpost pages: Chalk Peak (http://www.summitpost.org/chalk-peak/367551) and Penstock Ridge (http://www.summitpost.org/penstock-ridge/367537). The other three are known as as Lower Lytle Creek Ridge (http://listsofjohn.com/peak/63293) and Lower Lytle Creek, North (http://listsofjohn.com/peak/62174) and Upper Lytle Creek Ridge (http://listsofjohn.com/peak/60937).
Please be aware that this is an exploratory hike; much should be on easy fireroads, but occasional bushwhacking may be necessary.
Stats: 12 miles, 3000' gain.
UPDATE: bushwhacking up to Chalk Peak may involve a lot of whitethorn. We'll bring clippers and try to sneak around it...
