CrossClimb #915: Five Clues, One Sharp Ladder

The Route at a Glance

CrossClimb #915 rewards disciplined letter tracking. Each clued answer is four letters long, and every neighboring rung differs by exactly one letter:

FALL → CALL → CULL → BULL → BULK → BUCK → BACK

The key is not merely solving the clues. It is placing each answer so the word ladder remains unbroken.

Solving the Clued Rungs

1. CALL

The phrase “___ and response” gives CALL. This is the opening interior rung, and it immediately suggests a likely connection to FALL.

2. CULL

To remove something because it is the least useful part is to cull it. From CALL to CULL, swap the second letter: A becomes U.

3. BULL

A male elephant is a bull. From CULL to BULL, swap the first letter: C becomes B.

4. BULK

The majority portion is the bulk. From BULL to BULK, swap the fourth letter: L becomes K.

5. BUCK

To attempt to throw a rider off is to buck. From BULK to BUCK, swap the third letter: L becomes C.

Finding the Endpoints

Once CALL is in place, the upper endpoint must differ by one letter. FALL fits perfectly: from FALL to CALL, swap the first letter, changing F to C.

The lower endpoint is equally tight. From BUCK to BACK, swap the second letter, changing U to A.

The Final Aha!

The endpoint words form the compound pair FALL BACK, describing what some people do when Daylight Saving Time ends. The clue also warns that the first word may appear at the bottom, so the phrase must be read semantically rather than assumed from the grid’s orientation.

The completed climb is therefore:

FALL → CALL → CULL → BULL → BULK → BUCK → BACK

Every move changes exactly one letter, every middle rung answers its clue, and the two endpoints combine into the seasonal phrase that confirms the entire structure.
