I am fairly confident that "sinkhole" is the correct American spelling, 
and "sink hole" is discouraged; my guess is that's what the author was 
thinking.

That said, OSM apparently uses en_GB spelling, and "sink hole" *does* 
seem to have use in the UK (but it seems "sinkhole" does also).

FWIW, Wikipedia (https://en.wikipedia.org/wiki/Sinkhole) only lists 
"sink-hole" as an alternative, although Wiktionary does have "sink hole".

Interestingly, the etymology is given as 'from sinkehole, sinkeholl', 
suggesting that "sink hole" is a neologism and "sinkhole" is more 
historically accurate.
