On the other hand, mountains which are very heavily climbed or have popular trails up, such as Mount Whitney or Ben Nevis, may not have registers, or may have a daily log book that is changed out often.
The Sierra Club places official registers on many mountains throughout California and the United States.
These are typically small notebooks kept inside large metal boxes.
When registers are filled up, they are collected and stored in the Bancroft Library in Berkeley, California where they are available to view.
