We have just added a VR model of engraved petroglyph boulders in San Juan County Utah optimized for the Oculus headset.
This petroglyph site is in a naturally occurring rock shelter formed by boulders weathering from Comb Ridge. To view the site in VR, open this link [San Juan Model] in an Oculus or HTC headset browser.
You will see a headset icon in the bottom right of the model. Click that from inside the headset browser and enter the immersive VR space.
