If the batteries are of the same type, i.e. both are NiMH or both are Lithium-ion, then you can use a higher capacity (i.e. higher mAh) battery instead of the lower one. The reverse is also true.
People visiting Table Rock are not allowed beyond the Mill Creek Watershed boundary, which is clearly marked with numerous signs. As mentioned earlier, the Mill Creek Watershed is a closed watershed and no public access is allowed, as it is the municipal water source for the city of Walla Walla, Washington.
The trail rises gradually among rhododendrons, silver and noble firs. At a saddle, reach the Summit-Saddle Trail Junction, where there is a camp site but no water source. To reach the top of Table Rock, go left here and traverse up among mountain hemlock, western white pine, silver fir, Douglas-fir and noble fir. Bear-grass and huckleberries rim the trail.
