Humboldt House — formerly a resting area on the California trail and later a stage stop — I found this rusty horseshoe of unknown age.
I have no idea how to discover the age of a rusty old horseshoe, and it looks like a fairly standard one to me, not that I'm really in the know.

|A somewhat eroded tufa dome.|
Here I've stopped at a partly eroded tufa mound located north-northeast of the junction of U.S. 95 and I-80 (map and location below). It's fairly easy to reach with an SUV or other 4WD vehicle.
|View of the tufa mound looking northward toward the low hills of the Trinity Range.|

Embedding this map directly from Scribble Maps (see original map here); didn't work, so I imported the "scribble" to Google Maps.
To get to this particular tufa dome (there are many in the general area between a few miles east of Nightingale Hot Springs and Toulon), take I-80 exit 83 from either the eastbound or westbound lane. If going west, turn right nearly immediately (at a location known as Trinity, now with former buildings gone), and follow a paved road to the north-northwest. If going east on I-80, turn left from the off-ramp onto highway 95, go under the I-80 underpass, follow the road as it curves to the east, and turn left on the same paved road just before entering the on-ramp loop for Reno and points west.
Drive about 0.3 miles on the paved road until you reach a power line access road, a dirt road that may not be appropriate for cars. Turn right, taking this road for about 0.7 miles, including a deviation from the power line itself, where the original road is at least partly washed out. You will then reach just the right sand wash road, which will take you up to the tufa dome (and beyond to a small prospect). I can't say for sure that the turn I marked into the wash road is exact; look for tracks heading in the right direction.
Careful examination of a Google Maps or Google Earth view of the area will reveal another road that comes in from the west just uphill from the tufa dome. I have no idea whether this road will work as an access route, but it will (or would?) go past a couple other domes.
While there, note the several Lake Lahontan shorelines and the desert pavement.

"This month’s Accretionary Wedge topic is “Seeing Geology Everywhere.” Like many geologists, I often see geology in places where there are no rocks. ...
"Do you see geology in unexpected places? Do you often find yourself viewing the world through geology-tinted glasses? Do you have any adorable cat pictures that could be used to illustrate geology?"
– Evelyn Mervine, Accretionary Wedge #57 call for posts.

What happens now most commonly, is that I'll be working on some geological problem or project, and I'll start seeing textures or patterns related to certain rocks or maps in floor tiles, walls, trees, clouds, or anything else that happens to resemble some geologic texture or map pattern.
