15. Aerial view northeast of Phantom Ship, a small island remnant of andesite of phantom cone (unit apn; 403±12 ka nearby). Resistant, hydrothermally altered lava flows that form Phantom Ship are the top of a buttress on the submerged caldera wall whose southwest side appears to be bounded by a northwest-trending dike (Bacon and others, 2002). Caldera wall in distance features Sentinel Rock and Kerr Notch (Panorama J). Mount Scott (right) and Cloudcap (left) are on skyline.
