History

A post office called Mica was established in 1887, and remained in operation until it was discontinued in 1975.[3] The community was named for deposits of mica.[4]

gollark: Well, you can, or also "it would have about the same mass as the atmosphere".
gollark: Wikipedia says that spider silk has a diameter of "2.5–4 μm", which I approximated to 3μm for convenience, so a strand has a 1.5μm radius. That means that its cross-sectional area (if we assume this long thing of spider silk is a cylinder) is (1.5e-6)², or ~7e-12. Wikipedia also says its density is about 1.3g/cm³, which is 1300kg/m³, and that the observable universe has a diameter of 93 billion light-years (8.8e26 meters). So multiply the length of the strand (the observable universe's diameter) by the density of spider silk by the cross-sectional area of the strand and you get 8e18 kg, while the atmosphere's mass is about 5e18 kg, so close enough really.
gollark: Okay, so by mass it actually seems roughly correct.
gollark: So, spider silk comes in *very* thin strands and is somewhat denser than water, interesting.
gollark: You do that, I'll try and find data on spider silk density.
