Cueva de las Manos (Cave of Hands):

“…A cave or series of caves located in the province of Santa Cruz, Argentina…famous for the paintings of hands by indigenous inhabitants some 9,000 years ago. The composition of the inks is mineral and therefore cannot be carbon dated, so the age of the paintings was calculated from the bone-made pipes used to spray the paint onto the wall blocked by the hand.”

Not sure how old that quote is but I believe paintings can be dated using accelerator mass spectrometry

$lickypickysticky: This up to 1000 years old snow has metamorphosed into highly pressurized glacier ice that contains almost no air bubbles. Thus it absorbs the visible light despite the scattered shortest blue fraction, giving it its distinct deep blue waved appearance. This cavity in the glacier ice formed as a result of a glacial mill, or moulin. Rain and meltwater on the glacier surface is channelled into streams that enter the glacier at crevices. The waterfall melts a hole into the glacier while the ponded water drains towards lower elevations by forming long ice caves with an outlet at the terminus of the glacier. The fine grained sediments in the water along with wind blown sediments cause the frozen meltwater stream to appear in a muddy colour while the top of the cave exhibits the deep blue colour. Due to the fast movement of the glacier of about 1 m per day over uneven terrain this ice cave cracked up at its end into a deep vertical crevice, called cerrac. This causes the indirect daylight to enter the ice cave from both ends resulting in homogeneous lighting of the ice tunnel. But where is this?$
