Our friend Yoshiko Toyama took this stunning photo of an Aso peak, Nekodake. The peak, shown on the map at far right, had been thought to have formed after Aso went kablooee 90,000 years ago, creating the caldera. Turns out its rock is 150,000 years old, making it far older than the mountain we think of as “Aso” today, which formed after that eruption. If you’re considering climbing it, its highest point, Tengu Peak, is a steep rock peak, apparently requiring rock climbing skills. - William
