The cache is an ammo can. It has a logbook, some writing instruments and the usual assortment of trading items.
There is also a USGS benchmark atop the summit to log, as well as a bunker to check out built into the rocks just below the top that used to house radio equipment.
The road should be snow-free from June to whenever the mountain looks white from Colville. There are several different approaches to the summit road, check your maps before you go if you're not familiar with the area. The road can be passable by a 2WD with decent clearance, but 4WD is recommended.
The summit is accessible by snowmobile in the winter, but finding the container that time of year will require extra digging.
Please note the road to the summit has a major washout with no estimate if/when it will be repaired. For now this is a hike-in cache.
