| Trona Pinnacles National Natural Landmark |
Trona has two meanings, as a town in Inyo County, California and as a common name of a chemical
compound: trisodium hydrogendicarbonate dihydrate; Na3(CO3)(HCO3)•2H2O which is an evaporite
mineral. It is mined as the primary source of Sodium Carbonate in US. Trona Pinnacles has been designated
as National Natural Landmark in 1968.
Back in Pleistocene Ice Age, massive melt down of Sierra mountain made a series of inland lakes, including
Mono Lake, Death Valley and Searles Lake, which was to the west of Death Valley. The calcium rich ground
water of Searles Lake mixed with alkaline water made trona tufa formation.
There are four shapes of Trona Pinnacles: 1, Tower, tufa is a tall cylinder, higher than 30 ft.; 2,Tomstone,
stubby and squat, 20-30 ft., 3, Ridge, Massive toothy tufa runs as wide as 800 ft.; 4, Cones, dumty and
mounded, shorter than 10ft.
The Trona Pinnacles are located about 7 miles south of town of Trona, on unpaved road. But it is worth the
trip.
Approaching Trona from south on 395, some rock formations are very interesting.

I really appreciated the preservation of Trona Pinnacles as National Natural Landmark, we can visit the wonders
when we visit Southern California.
