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.
The act of recording a real estate deed enters the deed into public record. Once a document is in the public record, it is accessible through the Freedom of Information Act, but this accessibility is not always without restriction. In addition to the national Freedom of Information Act, each state has specific legislation that guides access to public records.
