In an attempt to investigate star formation activity and statistical properties of clumps of high Galactic latitude clouds (HLCs), we mapped the Polaris Flare region, PF121.3+25.5, in $^{12}CO;and;^{13}CO$ J = 1 - 0 using SRAO 6-m telescope and also observed its 12 $^{13}CO$ peak positions in CS J = 2 - 1 with TRAO 14-m telescope. $^{13}CO$ integrated intensity map shows clearly its clumpy structure and the locations of clumps well agree with $^{12}CO$morphology. CS line is not detected toward the 12 $^{13}CO$ peak positions, so we can conclude there are no dense $(sim10^4;cm^{-3})$ in this region. We decomposed 105 clumps from $^{13}CO$ map using GAUSSCLUMPS algorithm. The mass of clumps ranges from $7.8;M_{odot};to;7.4{ imes}10^{-2};M_{odot}$ with a total mass of $66.4;M_{odot}$ The mass spectrum follows a power law, dN/dM ${propto};M^{-alpha}$ with a power index of ${alpha}=1.91{pm}0.13$. The virial masses of clumps are in the range of $10{sim}100M_{LTE}$ and so these clumps are considered to be gravitationally unbound.
