[I used to shore dive in the Straits Of Juan de Fucca, Washington State side, and Crescent Lake - so I chose that area as a CoNED example to explore; good memories, including of the 18 Wheeler Burger with pie & coffee in Joyce, WA on drizzly days]

🚴‍♂️🔍🥱 So apparently, everyone was losing sleep over the "vital" need for more precise #elevation #data in GraphHopper's routing engine. Because, clearly, your #cycling route simply isn't complete without knowing that hill is exactly 2.34567 meters high. 🌍🚫

H/T Richard F. Ott
“The Chiribiquete are table top mountains located deep in the Colombian Amazon and host many rare endemic species. Helanlin Xiang's work shows that the Chiribiquete Mountains likely upifted before the Early Miocene and could have acted as a long-lived stepping stone, connecting species in the Andes with the Guyana Shield…”
