 In
March of 2017, an international team of cave explorers used a laser
scanner to measure a huge underground room in the Sierra Negra of
Puebla, Mexico...and discovered it was the fourth-largest subterranean
chamber in the world.

La Salón de la Muñeca Fea
(also known as La Muneca)
was discovered at the end of
Tlamanictli (also spelled Tlamanicitli) Cave
in 1999
by
Groupe Spéléo Alpin Belge.
My thanks to
Richard
Grebeude of GSAB
for his input.
The dimensions of this room were measured in 2017
by a Riegl
VZ-400
laser scanner
provided by the 3D Cave Project.
My thanks to Tim Allen and Andy Eavis for their help
and to Gustavo Vela for his great photos, video and excellent trip
report.
