  In this paper we present UBVRI CCD photometry in the region of two young open
star clusters Basel 4 and NGC 7067 for the first time. Our sample consists of ~
4000 stars down to V ~ 21 mag. Stellar surface density profile indicates that
radius of Basel 4 and NGC 7067 are about 1.8 and 3.0 arcmin respectively.The
(U-B) versus (B-V) diagrams indicate that metallicity of NGC 7067 is solar
while that of Basel 4 is Z ~ 0.008. We estimate the mean value of E(B-V) =
0.45$\pm$0.05 and 0.75$\pm$0.05 mag for Basel 4 and NGC 7067 respectively. The
analysis of 2MASS JHK data in combination with the optical data in both the
clusters yields E(J-K) = 0.30$\pm$0.20 mag and E(V-K) = 1.60$\pm$0.20 mag for
Basel 4 while E(J-K) = 0.40$\pm$0.20 mag and E(V-K) = 2.10$\pm$0.20 mag for NGC
7067. Furthermore, colour excess diagrams show a normal interstellar extinction
law towards both the clusters.
  Using the intrinsic colour-magnitude diagrams of the cluster members, we
estimated the distances of the clusters as 3.0$\pm$0.2 and 3.6$\pm$0.2 Kpc for
Basel 4 and NGC 7067 respectively. By fitting the proper metallicity isochrones
to the bright cluster members we estimated the age of the clusters as
200$\pm$50 and 100$\pm$25 Myr for Basel 4 and NGC 7067 respectively. The mass
function slope which is derived by applying the corrections of field star
contamination and data incompleteness are $1.55\pm0.25$ and $1.68\pm0.47$ for
Basel 4 and NGC 7067 respectively. The values of mass function slopes are thus
not too different from the Salpeter's (1955) value. Mass segregation is
observed in both the clusters which may be due to the dynamical evolutions or
imprint of star formation processes or both.
