Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres, as wide as 20 metres, and up to several hundred metres long.
When in outdoor public spaces where you are legally present, you have the right to capture any image that is in plain view (see note below about sound recording). That includes pictures and videos of federal buildings, transportation facilities (including airports), and police officers.
While the legal health record is generally the information used by the patient care team to make decisions about the treatment of a patient, the designated record set contains protected health information along with business information unrelated to patient care.
