The Sunyaev-Zel'dovich effect has the potential to identify high redshift galaxy clusters more efficiently than X-ray emission or optical/IR galaxy searches because the signal strength is only weakly dependent upon redshift, decreasing only when the cluster solid angle underfills the telescope beam. To date, however, no cluster has been confirmed that was discovered by the SZ effect, though several groups have apparent SZ signals from blank fields (Richards, et al 1997; Jones, at al 1997; Carlstrom, 2000). We wish to follow up such an SZ signal seen with SuZIE in December 1998. We have deep J and K-band near-IR images, but a null detection suggests a cluster with z > 1.3. We wish to take deep V and I-band images to search for cluster members out to z >~ 1.8. A null result will be equally as exciting as a detection of the cluster members, since it would indicate either a dark cluster or an extremely high redshift cluster (or both). The former case we may distinguish by weak lensing analysis of the field, which will be sensitive to intermediate redshift potential wells.
