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…”

[A very comprehensive hydrographic and shallow geophysical study and mapping effort of Lake Titicaca…]
“In October 2024, officers from the Category “A” Specialization Programme in Hydrography for Naval Officers of the Peruvian Navy conducted their complex multidisciplinary field project at Lake Titicaca at Puno in Peru, which is the highest navigable lake in the world (3,800 metres above sea level). The purpose of this survey was to address issues in the lacustrine environment due to hydrological processes that have occurred in recent years in this water body.…”

"... KEY POINTS
• A detailed local study of a system of seven previously unknown palaeolakes near the dichotomy in western Arabia Terra, Mars
• High resolution topographic data aids in identification and characterization of palaeolakes and regional hydrological history
• Evidence for a prolonged history of fluvial and lacustrine processes, with palaeolakes fed by groundwater and surface accumulation... "
