  Previous works on deformed graphene predict the existence of valley-polarized
states, however, optimal conditions for their detection remain challenging. We
show that in the quantum Hall regime, edge-like states in strained regions can
be isolated in energy within Landau gaps. We identify precise conditions for
new conducting edges-like states to be valley polarized, with the flexibility
of positioning them at chosen locations in the system. A map of local density
of states as a function of energy and position reveals a unique braid pattern
that serves as a fingerprint to identify valley polarization.
