When Grizzly River Run first opened as part of Disney California Adventure's original line-up, it included an extra soaking surprise after its climactic spinning drop.  If the splashdown didn't get riders wet, an unexpected geyser around the riverbend could!  This geyser didn't always go out, and many a river raft rider might float by unscathed. But when the jet of water did erupt--right under the river course itself--it typically spouted a deluge right onto adventurers.  As the ride aged, the geyser effect seemed to go away, at least in my memory.  But fortunately, after a refurbishment last year, the geyser returned, and it is still offering a splash-tacular surprise to guests who squeal in dread and glee as they see the impending shower.  It's nice to have that feature a part of the ride again, especially with the hot summer months upon us!
