New skylight and hornito developed about where former Cookie Monster once reigned. "Son of Cookie Monster" has been built in past week, following the surge in surface activity on January 21-22.
Looking across field of "carlitos," informal term for small hornitos, toward VLF training camp, where new workers are learning how to measure flux in lava tube using Very Low Frequency radio receiver.
Tiny hornitos, or "carlitos". Note thin glass filaments and points, formed by chilling of gassy lava spit from skylight. Discoloring is from sulfur and other minerals deposited by gas, as well as minerals formed by chemical alteration of glass by hot vapor. Carlitos form in dangerous areas, where roof on lava tube is thin. Solitary glove reminds us of this danger.
