Dating of a glaciogenic fan in the Cerro Azanaques massif (Bolivia, 18.91°S – 66.76°W – 3800 masl).
- class="label">•
Stratigraphic correlation and 14C dating yields a fan age of 16.07 ± 0.64 ka BP.

Mean in situ-produced 10Be concentrations of fan boulders 4.92 ± 0.05 × 105 at g−1.

Local (18.91°S – 66.76°W – 3800 masl) 10Be production rate is 30.8 ± 1.3 at g−1 yr−1 (SLHL P10 = 3.76 ± 0.15 at g−1 yr−1 Lm).

An internally-consistent reference calibration dataset combining three High Tropical Andes calibration studies is proposed.
