  Using high Reynolds number experimental data, we search for most dissipative,
most intense vortices. These structures possess a scaling predicted by
log-Poisson model for the dissipation field $\epsilon_r$. These new
experimental data suggest that the most intense structures have co-dimension
less than 2. The log-Poisson statistics is compared with log-binomial which
follows from the random $\beta$-model.
