Thank you, that's just interesting, never thought about how that could occur. It's worth seeing a satellite view of this from the various online maps. I found this mention of Wright's Point on a website, "Eastern Oregon Online" as well. https://spot.pcc.edu/~mhutson/mjames/wpoint.html
Another good example is North and South Table Mountains in the Golden Colorado area. The approx 64 Ma basalt flows (shoshonite) from a vent(s) up Ralson Creek overlying and interfingering with the Denver Formation. Neogene uplift induced erosion (especially Clear Creek) has separated the flows into North and South Table Mountains.

Thanks for sharing that. I used to live in Golden but don't have any good photos of the Table Mountains.
Here is a USGS pub but the images are all B&W. https://pubs.usgs.gov/sir/2006/5242/pdf/508SIR2006_5242.pdf
