Compensatory lengthening (CL) has traditionally been observed to be a purely local phenomenon, with the trigger and target segments being either adjacent to one another or separated by only one syllable boundary. In this talk, I present evidence from Estonian showing that CL can be long-distance (LD) as well, and provide an account that allows for LDCL while explaining its crosslinguistic rarity, as follows. If CL takes place, it is mediated by a constraint punishing the crossing of association lines (*CROSS), which enforces pure locality in CL. In Estonian, constraints forbidding unstressed long vowels (*VV) and geminates (*GEM) outrank *CROSS; morae are thus prohibited from landing in intermediate positions, and must travel longer distances to find a new home. LDCL is rare, then, because it only exists in languages that first enforce CL over mora deletion, and second, possess constraints that force LDCL over local CL.
