I can't go anywhere without looking for Survey Marks 🤣 I found 38 survey marks on my week-long vacation to Yosemite, read on to learn more!

Road Trip to Joshua Tree National Park! I built this entire trip around finding a single, hexagonal Gravity Station Survey Mark. Job Done!

Today's Mini Survey Mark Scavenger Hunt took me back to Point Loma and Cabrillo National Monument; adding two Lighthouses to my recoveries!
