I will have to try to find some pictures for you, but Blue Ribbon Pines #26 is a landscapers' dream when it comes to elevating a basket. It would require a enormous rocks.
Otherwise courses have used stumps or placing them in the trees; this can usually add about two to four feet of height, but that does not look like an option here as you have the basket in the open.
At a local small course, they just built up a mound of dirt, packed it down, and seeded it (to hold the mound). It created a quick elevation rise that ultimately was no more than 15 to 20 feet in diameter but raised the basket up by five feet.
I do not know how vandalism is in your area, but I have seen baskets placed on top of platforms like mini-decks/ balconies or on top of stands that you would use for hunting. It obviously looks very artificial and will upset a few people, but if it looks professional, it could become a marquee hole or very photogenic. It will also be a vandal magnet.
I am not sure how it would work here in this instance without making it look like a torture device, but I have also seen hanging baskets. Personally I do not like this idea, but again it adds that extra flare to the course to help distinguish it from other courses in the area.
Blue Ribbon Pines has many innovations to this problem. One solution they have tried for the past year or so is to hang a basket from a tree with a chain. You can also swing it from side to side for a challenging moving target.
