This entrance sign is at Hualapai Mountain Park in Arizona. This video was made on Pi Day 2017.

The entrance sign says...

+-----------------+ | <- Rec Area 1 | | Rec Area 2 | | Rec Area 3 | | Cabins | | <- Cabin 16 | | <- Camping | | Pioneer RV Park | | Hiking Trails | | <- Nature Trail | +-----------------+Because it was Pi Day 2017...

the numbers are: 1 2 3 16 the math is: 2^(1 + 3) = 16 more math: sqrt(sqrt(16)! + 1) - 3 = 2 more math: 16 % 3 + 1 = 2 rsPiEval: (1 + 2 + 3 + 16) / (16 - 3 * (2 + 1)) ~= Pi * 22/7 approximates Pi rounded to nearest hundredth (3.14) 3.1415926535897932384626 rsPhiEval: (1 + sqrt(3 + sqrt(sqrt(16)))) / 2 = Phi rsPhiEval: (1 + sqrt(2 + 3)) / sqrt(sqrt(16)) = Phi * Phi is the golden ratio and it approximates 1.61803399 rsAgeEval: (3!)^2 + sqrt(16)! - 1 = 59 * RoadHacker was 59 years young when he found this sign. rsStateEval: 3 * 16 * (2 - 1) = 48 * Arizona was the 48th state admitted to the Union. rs42Eval: 3 * 16 - (2 + 1)! = 42 * 42 is the "Answer to Life, the Universe, and Everything" rs37Eval: (3!)^2 + sqrt(sqrt(16)) - 1 = 37 * Whyrs37Eval? 37 Heaven @ http://thirty-seven.org rsCardinalityEval: 16 % 3 + 2 + 1 = 4 * There are four numbers in this sign.
