What are "dust-offs", you ask? They are simply active caches that haven't been found in a long time. Most times this is due to a high terrain rating or to a particularly remote location. Suprisingly, Arkansas doesn't have any really old dust-offs (none are older than one year, at least until January).
Here is a list of the top ten dust-off caches for Arkansas as of today, according to my research:
1) The Blue Hole Last found: 1/10/2004
2) Falling Water Falls Last Found: 1/14/2004
3) Brock Creek Trails Last found 1/31/2004
4) Night Eyes Last Found: 1/31/2004
5) Lost in the Dark Last Found 2/4/2004
6) Over the Edge Last Found 2/15/2004
7) The Battle of Marks Mill Last Found 2/26/2004
8 ) Artististic Matters Last Found: 3/26/2004
9) Swinging on the Mulberry Last Found: 3/28/2004
10) Just Add Water Last Found: 3/28/2004
Anyone up for the challenge of dusting off some of these?
