I'm not sure how much of an adventure you're looking for, but if you don't mind leaving pavement ...
When you're generally taking Hwy 95 north/south through Nevada, you can detour from the Walker Lake area and instead take Hwy 361 & Hwy 50. Near where 361 & 50 meet is Fariview Peak. You can drive (maintained dirt track) to the very top of this mountain and get stunning unobstructed views from 4000 ft above the surrounding terrain. Here's my van on the very top of Fairview Peak

Also nearby is a curious earthquake fault line you can see in person GPS: (39.2117, -118.1464)
