This crevasse is accessible from the Melissa Cliff site. Following the death of Daniel Laplante while diving on July 24, 2013, a plaque was forged in his honor and this rock formation was named after him. A commemorative plaque, made of varnished lead found by Daniel and provided by all his diving friends, was installed on the site.
