23782 12 Sep 2022 @ 1950 --- Graham Appears to be some wash between Rainbow Pool and Sunset Lake from a spot that was under the old boardwalk toward the new boardwalk. not sure how long it's been washed as this was my first visit after a guide said there was sinter on the boardwalk and dead bacteria mat in BSB. I saw none of that other than the small area of wash. Anyone else seen anything or knows if the wash is fresh?
