Cache is a bison tube. It contains only a logbook so please bring your own writing instrument and replace as found. According to https://www.geocaching.com/help/index.php?pg=kb.chapter&id=38&pgid=427 :
7.11. Respond to "throwdowns"
Throwdowns are strongly discouraged
A “throwdown” is a container placed by a geocacher who cannot find the original cache.
Some geocachers place throwdowns so that they can log a find on a cache that they suspect is missing. Geocaches should never be replaced without the permission of the cache owner. This can lead to multiple containers, geocacher confusion, and disputes about whether someone is entitled to log a find or not.
How to handle throwdowns
Cache owners are responsible for maintenance. When you are aware of throwdowns, check if your cache is still there and remove the throwdown cache. Consider disabling the cache until you can remove the throwdown or replace the original cache. If you do not disable the cache, you may want to honor Found It logs for the throwdown. However, the geocacher who placed the throwdown does not have a strong claim to log the cache as found.
