The clusters Cl 0023+0423 (z=0.84) and Cl 1604+4304 (z=0.90) are part of a multiwavelength program of Oke, Postman & Lubin (1998AJ....116..549O, Paper I) to study nine candidate clusters at z>~0.6. Based on these observations, we study in detail both the field and cluster populations. From the confirmed cluster members, we find that Cl 0023+0423 actually consists of two components separated by ~2900km/s. A kinematic analysis indicates that the two components are a poor cluster with ~3x10^14^M_{sun}_ and a less massive group with ~10^13^M_{sun}_. Cl 1604+4304 is a centrally concentrated, rich cluster at z=0.8967 with a velocity dispersion of 1226km/s and a mass of ~3x10^15^M_{sun}_.1998AJ....116..560Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/116/560CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/116/584 : Cl J0023+0423 and Cl J1604+4304 morphology (Lubin+ 1998)J/AJ/122/1125 : BVRI photometry in 3 high-z clusters (Postman+, 2001)http://archive.stsci.edu/mds/mds.cgi : HST Medium Deep Survey WFPC2 cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/116/560https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/116/560http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/116/560https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/116/560https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/116/560http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/116/560GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/116/560/table2Objects with spectra in the Cl J0023+0423 fieldrecnoRecord number assigned by the VizieR team.
