The best time of year to hike Angels Landing is in spring, summer and fall. Summer afternoons are very hot--get up early in the morning while temperatures are still cool. During winter the trail ices over and can be extremely dangerous. Do not hike during a thunderstorm--lightning will strike.
For other uses, see Memory (disambiguation). Memory is the faculty of the mind by which information is encoded, stored, and retrieved (Atkinson & Shiffrin, 1968). Memory is vital to experiences and related to limbic systems, it is the retention of information over time for the purpose of influencing future action.
As a result, your memories are not strictly constant, and are not always reliable. There are many different forms of long-term memories. These memories aren't formed and retained in a single part of the brain; instead, the process of creating and storing long-term memories is spread throughout multiple regions.
